"This year the world will make something like 70bn of these solar cells, the vast majority of them in China, and sandwich them between sheets of glass to make what the industry calls modules but most other people call panels: 60 to 72 cells at a time, typically, for most of the modules which end up on residential roofs, more for those destined for commercial plant. Those panels will provide power to family homes, to local electricity collectives, to specific industrial installations and to large electric grids; they will sit unnoticed on roofs, charmingly outside rural schools, controversially across pristine deserts, prosaically on the balconies of blocks of flats and in almost every other setting imaginable.

Once in place they will sit there for decades, making no noise, emitting no fumes, using no resources, costing almost nothing and generating power. It is the least obtrusive revolution imaginable. But it is a revolution nonetheless.

Over the course of 2023 the world’s solar cells, their panels currently covering less than 10,000 square kilometres, produced about 1,600 terawatt-hours of energy (a terawatt, or 1tw, is a trillion watts). That represented about 6% of the electricity generated world wide, and just over 1% of the world’s primary-energy use. That last figure sounds fairly marginal, though rather less so when you consider that the fossil fuels which provide most of the world’s primary energy are much less efficient. More than half the primary energy in coal and oil ends up as waste heat, rather than electricity or forward motion.

What makes solar energy revolutionary is the rate of growth which brought it to this just-beyond-the-marginal state. Michael Liebreich, a veteran analyst of clean-energy technology and economics, puts it this way:

In 2004, it took the world a whole year to install a gigawatt of solar-power capacity... In 2010, it took a month In 2016, a week. In 2023 there were single days which saw a gigawatt of installation worldwide. Over the course of 2024 analysts at BloombergNEF, a data outfit, expect to see 520-655gw of capacity installed: that’s up to two 2004s a day...

And it shows no signs of stopping, or even slowing down. Buying and installing solar panels is currently the largest single category of investment in electricity generation, according to the International Energy Agency (IEA), an intergovernmental think-tank: it expects $500bn this year, not far short of the sum being put into upstream oil and gas. Installed capacity is doubling every three years. According to the International Solar Energy Society:

Solar power is on track to generate more electricity than all the world’s nuclear power plants in 2026 Than its wind turbines in 2027 Tthan its dams in 2028 Its gas-fired power plants in 2030 And its coal-fired ones in 2032.

In an IEA scenario which provides net-zero carbon-dioxide emissions by the middle of the century, solar energy becomes humankind’s largest source of primary energy—not just electricity—by the 2040s...

Expecting exponentials to carry on is rarely a basis for sober forecasting. At some point either demand or supply faces an unavoidable constraint; a graph which was going up exponentially starts to take on the form of an elongated S. And there is a wide variety of plausible stories about possible constraints...

All real issues. But the past 20 years of solar growth have seen naive extrapolations trounce forecasting soberly informed by such concerns again and again. In 2009, when installed solar capacity worldwide was 23gw, the energy experts at the IEA predicted that in the 20 years to 2030 it would increase to 244gw. It hit that milestone in 2016, when only six of the 20 years had passed. According to Nat Bullard, an energy analyst, over most of the 2010s actual solar installations typically beat the IEA’s five-year forecasts by 235% (see chart). The people who have come closest to predicting what has actually happened have been environmentalists poo-pooed for zealotry and economic illiteracy, such as those at Greenpeace who, also in 2009, predicted 921gw of solar capacity by 2030. Yet even that was an underestimate. The world’s solar capacity hit 1,419gw last year.

Note: That graph. Is fucking ridiculous(ly hopeful).

For perspective: the graph shows that in 2023, there were about 350 GW of solar installed. The 5-year prediction from 2023 said that we'd end up around 450 GW by 2030.

We hit over 600 GW in the first half of 2024 alone.

This is what's called an exponential curve. It's a curve that keeps going up at a rate that gets higher and higher with each year.

This, I firmly believe, is a huge part of what is going to let us save the world.

Understanding the meaning, applications, and advantages of control valves.

Control valves are devices that play an essential role in controlling and regulating the flow, pressure, and temperature in industrial processes and control systems. It is installed in the field-level area of the automation pyramid and connected to the control system and PLC through the PLC’s hardware. The global control valve consists of the body, actuator, Positioner, Valve trim, stem, and bonnet to prevent leakage. There are also the Gaskets and seals that are used when connecting the valve with other mechanical parts.

Control valves have many advantages such as Accurate Control of Process Parameters, Easy Automation Compatibility by integrating these items with the main Control systems (DCS and PLC), Energy saving and energy efficiency by optimizing the process condition and minimizing waste, maintaining safe operating conditions and increase process safety factors, Improve Process Efficiency and Increase Product Quality.

Control valves are used in many applications such as the Automotive Industry, Cement and steel, and Oil and Gas Industry, especially in gas valve trains, Renewable Energy, and HVAC Systems.

The Global Renewable Energy Market in mining is expected to grow significantly, with a projected revenue increase of USD 3.4 billion by 2032, driven by a compound annual growth rate (CAGR) of 8.4% from 2023 to 2032. In 2022, the Asia-Pacific region led the market, holding over 39% of the renewable energy share within the mining sector.

Ingenting for Norge

Following the general move towards a renewable future, Norway elects a green government. The green government seeks to shut of the oil and set a shinning example of all European nations to follow, by investing in greener alternative energy sources.

The EU displeased with Norways sudden shutting down of the oil applies draconian sanctions upon Norway. Combined with the dissolution of nato following trumps presidency The EU begins to move more towards Russia and Norway finds itself increasingly isolated.

Following the assassination of the Norwegian prime minister, the EU collectively with the Russian Federation present an ultimatum to Norway. Demanding that they let Russian businesses work with Norway to turn the oil back on to give Europe time to transition to renewables. Russia would then withdraw after Norway’s oil production became sufficient again. Norway seeing no other choice agree’s to the demands.

Norway faces months of instability with many terrorist attacks, this results in Russia prolonging it’s stay.

The instability eventually leads to the government going into free fall, and a military coup. The military coup results in a Russian invasion aiming to bring stability to Norway and to protect the oil supply to Europe.

As a result of Norways divisions and political turmoil the nation collapses in on itself.

And thus the sun sets on Kingdom of Norway, it engulfed in the flames of civil war.

"Enviornmental campaigners have welcomed Labour’s decision to lift the Tories’ ban on new onshore wind developments.

In one of the new government’s first acts, the department for energy and net zero confirmed that future projects will be treated in the same way as other planning applications.

Energy secretary Ed Miliband said: “The onshore wind ban has been in place for more than nine years. We’ve been in government 72 hours, we’ve lifted it.

“That’s the pace we’re going to move at. We’ve got to become a clean energy superpower for energy independence, to cut bills, to create good jobs and tackle the climate crisis. We’re getting on with it.”

“By harnessing the country’s vast renewable power potential, the new government is staking its claim as a global leader in the green energy transition.”

Chancellor Rachel Reeves confirmed the change as she also announced major changes to the planning system to allow the building of more homes as part of the government’s moves to boost economic growth."
