Excerpt from this story from Canary Media:

When we think of solar, we tend to picture shimmering expanses of panels spread across farmland or mounted on rooftops. But how about attached to a raft, floating atop a reservoir?

Floating solar photovoltaics, also called ​“floatovoltaics,” is an emerging technology that’s taken off in countries across Asia and Europe, especially near urban areas with limited space available for land-based solar.

It’s also an untapped resource for the U.S. clean energy transition, according to a new study by researchers at the Department of Energy’s National Renewable Energy Laboratory. They found that federally owned or managed reservoirs could hold enough floating solar to produce up to 1,476 terawatt-hours of clean electricity — enough to power about 100 million homes each year.

“We know we’re not going to be able to develop all of this. But even if you could develop 10% of what we identified, that would go a long way,” said Evan Rosenlieb, geospatial scientist and study co-author.

Even under the most conservative scenario the researchers considered, the potential of floating solar equals more than half of the solar capacity required for a fully carbon-free grid in the U.S. in 2050.

Besides minimizing land use, floating solar shades water bodies, which reduces evaporation and conserves limited water supply at reservoirs. Water also cools down the panels, making them up to 15% more efficient than land-based solar.

But so far, floating solar only makes up a tiny fraction of the U.S. solar market and is mostly limited to small-scale projects, including at a wastewater treatment plant in Healdsburg, California; a reservoir in Cohoes, New York; and a lake at the Fort Liberty military base in North Carolina. The country’s largest floating solar project is an 8.9-megawatt installation at a water treatment plant in Millburn, New Jersey.

Compare that with projects like Thailand’s 45-MW floating solar farm in the Sirindhorn Dam reservoir, or China’s massive 550-MW system that sits atop a body of water used for fish farming in the city of Wenzhou. ​“In the United States, we don’t have a single project over 10 MW,” said study co-author Aaron Levine.

Dominion Energy’s 1.6 MW Black Bear Solar project in Buckingham County is now partnered with Mountain House Apiaries, using Italian honey bees to maintain the land around the solar arrays while benefiting the local agricultural community.

The project falls under the category of agrivoltaics — another way to label pairing solar panels with agricultural uses — and is an effort by Dominion to show and see how solar can live in harmony with the land and surrounding agriculture industry. 

“A lot of people are very, very passionate about making sure the area stays agricultural,” said Adam Fillius, electrical distribution program manager at Dominion Energy, while out on a tour of the facility. “If you can provide them with clean energy and still be able to stay agricultural. That’s a win for everybody.”

The honey bee, which almost became the state’s official pollinator species by way of legislation earlier this year, is lost at a 35% rate each year, but has spiked up to a 48% loss in one year.  Honey bees are needed for about one-third of all food production.

“There’s plenty of feral bees out there, ones that live in the tree,” said Chuck Burden, beekeeper at Mountain House Apiaries. “The honey bees are endangered.”

Interconnecting with honey

The $7.5 million solar project, which can produce enough electricity to power 400 homes, came online in 2023 after the State Corporation Commission approved it as one of the first projects proposed under the VCEA.

Through a mutual contact, Fillius got connected with Burden, who reviewed some online maps to see if there were other bee farms within a five-mile radius, since bees travel within this range, that might create competition for food. He also checked to see what farms are in the area that might use herbicides, pesticides or insecticides. 

Buckingham County, located in the middle of the state, has 375 farms totaling about 80,900 acres with an average of about 216 acres per operation, according to the United States Department of Agriculture, but Burden said he didn’t find any conflicts.

“Part of my thinking is the solar farms don’t do herbicide spraying or insecticide spraying, so the earth that they’re sitting on, regardless of what it was used for prior to, is allowed to heal and get back to its natural state,” he said. Burden also saw added appeal from the security fence and trees surrounding the facility to protect the bees from bears.

Dominion has a requirement to have a percentage of their seed mix be pollinator friendly, which helps the bees, Burden said. That resulted in a traditional turf mix planted under the panels surrounded by native pollinator plants: white clover, little bluestem, black-eyed susan, eastern columbine, lance leaf coreopsis and more.

“Keeping all the clover and the other pollinators that we have mixed in with this grass that’s growing here, it’s a big benefit,” said Steve Voreh, compliance program manager in the renewable energy department with Dominion. “You can see here there’s almost no erosion at all, just a nice big green field with clover and other pollinators.”

Busy bees

Since August, the about 14-acre site Dominion Energy leases – has been home to about 45,000 bees in each of the about four hives made with wood and nailed together at the corner joints, for a total of about 180,000. 

Burden bears the costs of the bees, with room to add another four hives and possibly up to 24 across the whole site. He’ll check on them by testing the pollen for chemicals and weighing them to make sure they get enough food. He’ll harvest about 20 pounds of honey, with about 60 to 80 pounds left so the bees can make it through the winter. 

The hives join the roughly 200 that Burden has at 10 locations across the state to sell product at his shop on State Route 151 in Nelson County, turn it into mead or let his daughter consume it to avoid her needing daily allergy shots.

“Virginia is probably the allergy capital of the world,” Burden said.

The goal

Tension between solar developers and the farming community is centered around the Virginia Clean Economy Act, a 2020 law that seeks to transition Dominion to renewable generation sources that don’t emit climate changing emissions by 2045. 

Developers want to build, but farmers are concerned about land loss and disturbances.

The idea of honey bees is an extension of other agrivoltaics efforts that use sheep to rotationally graze about 40 acres of land every few days, and potentially planting crops on the middle of panels after more research is done.

“Dominion is very focused on looking at agrivoltaics right now with its solar farms,” said Tim Eberly, a Dominion spokesperson. “We’re exploring other sites where we could put bee hives.”

“Dominion is very focused on looking at agrivoltaics right now with its solar farms,” said Tim Eberly, a Dominion spokesperson. “We’re exploring other sites where we could put bee hives.”

Martha Moore, senior vice president of governmental relations with the Virginia Farm Bureau who has pushed for legislation to preserve farmland, said the concept of agrivoltaics is “interesting,” but the jury is still out as Virginia Tech conducts research on the viability of the concept.

“We’re certainly open to the discussion,” said Moore, while also wanting some more details:  “What does that entail? How is it economically viable for farmers?”

But for Burden, the project with Dominion is a “very promising” part of the transition to a natural environment.

“The other thing that’s promising is, what better opportunity do you have to be right in the middle of all the farmers to help educate them to strike a balance?” he said.

Tech Talk 101: Solar Glossary for Beginners - GB Solar

Solar energy is, to be sure, a whole new language to learn, filled with wires and watts and lots of wonderful things! Be it solar panels atop your roof or trying to make sense of your energy bills, understanding solar jargon could make or break the deal for you. You needn’t be an engineer or a person who is an expert in solar backgrounds to do it, so fear not. Let us break it down in layman’s terms for the benefit of your solar-gleaming knowledge!

The Basics: Back to Science Class!

Let’s warm up with some simple concepts you may vaguely remember from school:

Current (I): Imagine electricity as a river, and current is how fast the water (electrons) flows. There are two types—Alternating Current (AC) and Direct Current (DC). The SI Unit of current is Ampere (A)

Alternating Current (AC): This is what powers your home. It flows back and forth, changing direction—like waves lapping on a shore.

Direct Current (DC): DC is straight to the point—electricity flows in one constant direction, just like the energy from batteries or solar panels

Voltage (V): Think of this as the “pressure” pushing electricity through a wire. More voltage means more power pushing electrons from one point to another. The SI unit of Voltage is Volt (V).

Power (W): This is how fast energy is used or generated. The SI Unit for Power (W) is Watt.

        1 kilowatt (kW) = 1,000 watts

        1 megawatt (MW) = 1,000 kW

        1 gigawatt (GW) = 1,000 MW

Kilowatt-Hour (kWh): This is the “unit” seen on your electricity bill. A 1 kilowatt appliance used for one hour is one kWh consumed. Monitor your household appliances, and very soon, you will find out how much solar power you might need!

Utility Grid: The giant web that sends power from big power plants to your home or office. It’s what you’re currently plugged into.

Solar Panel Speak: Your Intro to Solar Modules

Now let’s zoom in on the stars of solar power—the panels and their partners:

Solar Panel: Photovoltaic panels are made up of photovoltaic (PV) cells, which are converters of sunlight into electricity, typically by using silicon. Connect a whole bunch of them together and you’ll get a solar array.

Solar Inverter: Solar panels do produce DC power, but home electricity runs on AC. So in between comes the inverter that operates conversions of the two, hence rendering solar power usable.

Balance of System (BoS): Everything in your solar setup except the panel—like cables, mounting frames, batteries, and wiring. The unsung heroes!

Panel Efficiency: This tells you how good your panel is at converting sunlight into electricity. The higher, the better. GB Solar offers 20–23% efficiency—top-tier stuff!

Bifacial Panels: Unlike traditional panels that work from one side, bifacial ones capture sunlight from both the front and back. More sun, more power!

Monocrystalline Panels: Sleek and black, these are made from a single crystal of pure silicon. They’re efficient and premium, but also a bit pricier.

Polycrystalline Panels: Blueish and made from multiple silicon crystals, these are more budget-friendly but slightly less efficient.

Solar Tech Innovations: PERC vs. TOPCon

PERC (Passivated Emitter and Rear Cell):

Imagine your solar cell is a bucket catching sunlight. PERC adds a reflective layer to the bucket’s base, so nothing escapes—more light captured, more energy made.

TOPCon (Tunnel Oxide Passivated Contact):

Now imagine an ultra-bucket that reflects, catches, and transfers light faster with minimal loss. TOPCon cells are energy efficiency champions, especially in hotter climates.

Solar System Types: Know Your Setup

Grid-Tied (On-Grid) Systems: Stay connected to the grid while using solar energy. If you produce extra, you can send it back and earn credit!

Off-Grid Systems: No grid? No problem. These standalone systems use batteries to store energy for night-time or cloudy-day use.

Hybrid Systems: Best of both worlds—connected to the grid and equipped with battery backup for added reliability.

Rooftop Solar: Popular among residential and small commercial spaces. Easy to install, easy to maintain—just keep it clean!

Ground-Mounted Solar: Perfect for high-capacity projects. The panels are installed on sturdy ground structures, ideal for farms and industrial plants.

Solar Policies & Financial Terms (aka Money Talk)

Here’s where solar meets your wallet. These terms are worth knowing:

Net Metering: Produced more power than you used? Send it to the grid and get credited for it!

Gross Metering: All your solar power goes to the grid, and you receive a fixed rate for every unit.

Feed-in Tariff (FiT): A guaranteed price you get paid for the solar energy you export to the grid.

Time-of-Day (ToD) Tariff: Electricity costs shift depending on demand—cheaper at night, costlier in the evening.

Renewable Purchase Obligation (RPO): Big consumers are legally required to source a portion of their energy from renewables.

Open Access Solar: Large businesses can buy solar power directly from producers, bypassing the local utility.

Electricity Duty Exemptions: Incentives like zero duty charges make solar even more affordable.

Power Purchase Agreement (PPA): A contract to sell solar power at agreed rates—usually signed between producers and DISCOMs.

Accelerated Depreciation: A big reason solar is great for industries—you get tax benefits by writing off the project cost quickly.

Capital Subsidy: Government support to reduce initial solar setup costs—makes the transition more budget-friendly.

Renewable Energy Certificates (RECs): Certificates that prove you’ve generated green energy. They can be traded or used to meet RPOs.

Green Bonds: Investors fund green projects like solar plants through bonds. Good for your karma and your portfolio!

Solar Investment Tax Credit (ITC): A tax benefit allowing you to deduct a portion of your solar investment from your income tax.

Bankable Solar Projects:A project that’s profitable, stable, and attractive to investors.

Levelized Cost of Energy (LCOE): The average cost of electricity from your solar system over its lifespan—a great metric to understand ROI.

Ready to Go Solar?

What is now making you feel a little better with the solar lingo? Rather, learn your solar ABCs and make wiser green choices whether it is to go totally off-grid or just reduce electricity bills.

The Rise of Floating Solar Technology in India

As the world grapples with climate change and a growing demand for clean energy, innovation in renewable energy has taken center stage. One of the most promising advancements in recent years is floating solar technology—a solution that utilizes water bodies to generate electricity through solar panels mounted on floating platforms.

India, with its ambitious renewable energy targets and vast network of reservoirs, lakes, and dams, is emerging as a key player in this space. The country’s geography and climate make it an ideal candidate for scaling this innovative technology, and several floating solar companies in India are already leading the charge.

What is Floating Solar Technology?

Floating solar, also known as floating photovoltaic (FPV) systems, involves installing solar panels on water bodies like lakes, reservoirs, and industrial water storage facilities. These floating solar arrays are anchored to ensure they stay in place and can be scaled depending on the size of the water body.

This technology offers several advantages:

Land conservation: No need for large land parcels.

Increased efficiency: Water cools the panels, improving performance.

Reduced water evaporation: Panels act as a shield, preserving water in reservoirs.

Environmental benefits: Lower impact on local ecosystems compared to land-based installations.

Growth of Floating Solar in India

India is targeting 500 GW of non-fossil fuel energy capacity by 2030, and floating solar is expected to play a significant role in achieving this goal. With over 5,000 large dams and countless other water bodies, India has the potential to install over 280 GW of floating solar capacity.

Some of the largest floating solar companies in India are already developing or operating key projects:

1. NTPC Limited

India’s largest power utility has launched several floating solar projects across states like Kerala, Madhya Pradesh, and Andhra Pradesh. Its 100 MW plant at Ramagundam, Telangana is one of the biggest in the country.

2. Tata Power Solar

A subsidiary of the Tata Group, Tata Power Solar has ventured into floating solar projects and has been involved in both government and private sector initiatives.

3. ReNew Power

This renewable energy giant is exploring FPV systems as part of its diversification strategy. ReNew Power’s innovative approach to large-scale clean energy projects includes floating solar deployments in states like Maharashtra and Karnataka.

4. Adani Green Energy

Adani Group, a major player in India's solar sector, is exploring floating solar options to complement its vast portfolio of land-based solar installations.

5. Jakson Group

Known for its EPC services in solar energy, Jakson has expanded its offerings to include floating solar technology and has partnered with various public and private entities to deploy FPV systems.

Challenges and the Road Ahead

While promising, floating solar technology in India faces challenges including high initial costs, technical complexities in anchoring and maintenance, and the need for policy clarity. However, with increasing R&D investment, falling solar panel costs, and growing support from the government, these hurdles are expected to diminish.

The Ministry of New and Renewable Energy (MNRE) has recognized the potential of floating solar and is encouraging public sector undertakings (PSUs) and private companies to invest in this domain.

Conclusion

As India continues its journey toward a greener future, floating solar technology stands out as an innovative and practical solution to meet rising energy demands while conserving land and water resources. With a growing number of floating solar companies in India stepping up to the challenge, the country is well-positioned to become a global leader in this transformative sector.

[necarion]

The US generated about 4200 TWh of electricity in 2022, which comes to an average of about 480 GW, the majority of which is consumed during the daytime. Stationary solar panel arrays claim about 0.5 MW/acre, but this number is also for, like, average in the whole US. That number will be a lot higher in the desert and with movable panels, but let's just run with that.

To generate 480 GW (there are going to be other sources of power, such as at night, but this is going to represent around a doubling of daytime capacity), using that lower bound estimate requires about 1,500 mi^2 of area.

Now, that's admittedly quite a lot, bigger than the state of Rhode Island. But the Mojave Desert is about 48,000 mi^2, and that is only a tiny fraction of the bright red area listed above. If we provided that rough-doubling of electricity, and put that entirely in the Mojave, we're taking about 3% of the land area.

We are not going to be driving entire species to extinction with that sort of land use

Also, I suspect that if we decided to put the entirety of that solar energy in the Navajo nation (taking up about 6% of that land area) you'd actually have significant (obviously not unanimous) support among the Navajo by giving them some degree of control of such a massive amount of electricity production. I am not saying we just shove it there without permission, but if they ask for permitting permission and transmission lines, we should 100% give it to them and buy their energy.

Yes, there will always be wildlife in any sort of area we build. But I can guarantee that the cost to those ecosystems will be higher with increased global warming. And of all the ecosystems you could be damaging by covering over the land with solar panels, you can do a hell of a lot worse than the Mojave and Nevada deserts. Basically the only place you could do better for wildlife displacement would be on currently-used agricultural land, and there are significant barriers to doing that, such as the farmers not currently wanting it there.

If we only limit green energy to types that don't harm any environment, you're putting the panels in developed areas where they are (a) way less efficient, (b) way more expensive, and (c) generate more local opposition. We cannot solve global warming if we end up with NIMBY for all green energy, where "my backyard" means "everywhere".

.....

As a side note, this keeps coming back to this annoyance I have, which is that, to some extent, the scale for solving the green energy problem is actually smaller than we think, as long as we just let people do it. We can do tons of geothermal production, if we didn't thwart all sorts of drilling. We can mine tons of lithium, if we don't block mining sites on environmental grounds. We only need like 40 Saudi-scale desalination plants to provide all of Arizona's water needs. Since that plant uses about 200 MW to desalinate the water, that comes to about 4 GW of power, or 1% of what we needed above (about 12 mi^2 of solar plant area, or one nuclear power plant), if we allowed the construction of desalination plants (we worry about marine ecosystems, and then drain the rivers). We can build artificial reservoirs, fill them with desalinated water, and use them both for storage of water and for pumped hydro electrical storage.

If there legitimately is a climate emergency. If stopping global warning really is existential. If nothing is more important. Then we, who care about the environment, have to be willing to make sacrifices, to allow some ecosystems to be scathed.

And it will turn out that (a) the ecosystems will be less scathed if we get global warming under control, and (b) there is so much less scathing going on than the environmental movement fears.

The Joshua tree is on its way to extinction because so-called green energy companies want to keep the death machine of civilization going by installing large swaths of solar panels over the desert floor, a big metal blanket that will kill everything it covers: the desert tortoise, the sage grouse, the hawks and snakes and beautiful flowers that have flourished for thousands of years. Gone. Gone.

All so that we can keep the dead heart in the rotting corpse of industrial civilization beating into the next decade. These are the "good guys" btw, these are the "renewable" "carbon neutral" options: covering the desert in miles of metal and microchips until every living being without a bank account is dead.

The Science Behind Solar Panels: How Do They Generate Electricity?

At the core of every solar panel lies the ingenious process of photovoltaics, which is responsible for converting sunlight into electricity. This process takes place within the solar cells and it is essential to comprehend how it works.

Semiconductors at Play: The Building Blocks of Solar Cells

Solar cells are primarily constructed using semiconductors, with silicon being the most commonly used material. These cells are engineered with two distinct layers—a negatively charged layer and a positively charged layer.

Let's take a closer look at how these semiconductors contribute to electricity generation.

The Role of Sunlight: The Catalyst for Power Generation

When sunlight, in the form of photons, strikes the solar panels, it triggers a chain reaction. Understanding the interaction between photons and the semiconductor material is key to comprehending how solar panels operate.

Electron Liberation: How Solar Panels Set Electrons in Motion

The energy from absorbed photons empowers the electrons in the negatively charged layer to break free from their atomic bonds. As they gain energy, these electrons start to move, creating a flow of electricity.

Channeling Solar Power: Capturing and Utilizing the Generated Current

The electric current generated through this process can be harnessed and directed to power a variety of devices, homes or businesses. This section delves into how the electricity produced is utilized.

В Англии открыта очередная солнечная электростанция на парковке. Крыша автостоянки из солнечных панелей расположенных на стальных опорах, собирает энергию солнца используя уличную парковку. Более 2,000 панелей с пиковой мощностью 1 мегаватта (МВт), этого достаточно, чтобы обеспечить энергией сотни домов. Солнечные автостоянки или автомобильные порты позволяют производить электроэнергию на открытых пространствах, которые, как правило, удобно расположены рядом с энергоемкими объектами, такими как больницы, торговые центры или офисы. Козырьки имеют дополнительные преимущества в том, что они защищают автомобили от дождя и снега или жаркого солнца летом. Солнечные автостоянки существуют уже много лет, и есть признаки того, что они начинают процветать здесь, поскольку цены на электроэнергию в настоящее время все еще высоки, многие предприятия обращаются к возобновляемым источникам энергии на местах, чтобы попытаться снизить затраты в долгосрочной перспективе. Существует возможность для компаний владеющих парковкой трансформироваться в энергетическую фермы. Великобритания в настоящее время имеет в общей сложности около 15 ГВт солнечной мощности, планируется получать 40 ГВт к 2030 году для достижения целей чистого ну��я, данные Solar Energy UK. Why car parks are the hottest space in solar power There's more than just cars and empty spaces in this car park. Huge arrays of angled solar panels sit atop jet black steel supports, soaking up the sun and shading the vehicles beneath. Outside the offices of a major car manufacturer in the south of England, there are now more than 2,000 panels in total with a peak capacity of just under 1 megawatt (MW). That's enough to power hundreds of homes. There is a huge opportunity to turn more British car parks into solar farms, according to a new report published by the countryside charity CPRE and the UCL Energy Institute. For context, the UK currently has around 15GW of solar capacity in total and requires 40GW by 2030 in order to meet net zero targets, according to Solar Energy UK. UK business news. ONLYWAY.NEWS

Ozarks Electric Couples Battery Energy Storage with Springdale Public Schools Solar Array to Maximize the Harvesting of Clean Energy for Members and Students Alike

SPRINGDALE, Ark. — Ozarks Electric Cooperative and Springdale Public Schools flipped the switch Monday on their new solar and battery storage facility alongside Today’s Power, Inc. (TPI), which installed and will own and operate the systems. Solar power paired with battery energy storage systems is advancing leaps and bounds in the effort to increase savings and maximize the harnessing of clean energy.

The 2.375 megawatt solar array consists of more than 7,000 panels on 15 acres of land near Sonora Middle School in Springdale. The panels include technology that allows them to track the movement of the sun to maximize generation. The project also contains 6.9 MW of battery storage to be used by Ozarks Electric.

Combining solar generation with battery storage will allow Springdale schools to offset about 95% of the total energy consumed by Don Tyson School of Innovation, Sonora Middle School and Sonora Elementary School while helping Ozarks reduce its wholesale demand costs. The power generated by the solar panels will result in significant savings for the school district, while Ozarks can utilize the stored battery power to be used during peak times, thereby reducing wholesale demand charges and controlling costs for members demand prices (or charges) and controlling costs for their members. Ozarks and TPI have demonstrated this concept with previous similar projects, which include the city of Fayetteville wastewater treatment system and the Ozarks Multi-Industry solar park.

“Ozarks Electric Cooperative and Today's Power have knocked it out of the park for Springdale School District with the new solar farm,” said Jared Cleveland, Springdale Public Schools Superintendent. “The Sonora Elementary and Sonora Middle School students have watched the construction project with anticipation over the last year and now see the amazing technology in operation. The solar farm is not only a STEM Learning tool for our students but also an investment in our community. It provides an avenue for Springdale Public Schools to reduce our carbon footprint all while saving critical tax dollars that can be reinvested in our students. I am grateful for Mitchell Johnson for bringing this fantastic opportunity to his home school district.”

Derek Dyson, CEO of Today’s Power, Inc. said “TPI is excited to continue to work with Ozarks Electric Cooperative and Springdale School District on implementing this exciting project. TPI’s success is due to our relationships with entities, such as Ozarks and Springdale.  By working together, TPI further demonstrates the value of being cooperative owned and community focused in completing this facility within a timely and cost-effective manner. TPI looks forward to future opportunities to serve this community.”

Mitchell Johnson, president and CEO of Ozarks Electric, said the project is an example of how innovation and collaboration can benefit cooperative members and the community.

“Working together, we can meet the energy needs of our region and add renewable resources while continuing to provide reliable, affordable power for our members,” Johnson said. “I am proud of our partnership with TPI and Springdale schools, and look forward to future projects.”

Excerpt from this story from Las Vegas Review-Journal:

The first environmental review is out for the nation’s largest solar power array, and conservationists are already pushing back against the proposed project 30 miles northeast of Las Vegas.

If approved, the Gemini Solar Project would use 7,100 acres of photovoltaic panels to generate up to 690 megawatts of electricity. Plans include some on-site battery storage that would allow the facility to continue delivering power after the sun goes down.

The Bureau of Land Management released its draft environmental impact statement on the project Thursday. The agency will hold a pair of public meetings in July and accept public input on the document through Sept. 5.

Kevin Emmerich, director of the Nevada-based environmental group Basin and Range Watch, said the proposed development is too large and too close to wilderness and other fragile areas to avoid negatively impacting the environment.

He said he’s all for green energy, “but it’s not green when you do it like this.”

Gemini is a joint venture by Australia’s Quinbrook Infrastructure Partners and California-based Arevia Power, which plan to develop 440 MW of solar capacity for use in Nevada in the first phase of the planned development east of Interstate 15 along the road to Valley of Fire State Park.

Another 250 MW of generating capacity would be added in the second phase, with the power to be sold in Nevada or exported to Arizona and California.

Emmerich said the developer’s surveys suggest that almost 300 desert tortoises will have to be relocated during construction. He said the federally protected reptiles face higher mortality rates when they are moved, because they expose themselves to predators and the elements while trying to make it back to their old homes.
