Ultimately, every bit of energy in the world comes from the sun. He is the reason why plants and animals turned into fossil fuels. Solar power is the source of all our food, our energy for transportation systems, and the energy needed to run industries. While we think of water and wind as renewable energy sources, in the final analysis they also depend on the sun.
If the world is interested in sustaining itself, increasing the energy we harvest directly from the sun is the most efficient way to do it. According to Bloomberg New Energy Finance’s latest Energy Transition (paywall) report, 182 GW of new solar was added worldwide last year – nearly half of all new capacity. Wind took up an additional quarter of the new capacity. “Wind and solar are now the cheapest sources of large-scale electricity generation in countries that account for two-thirds of the world’s population and three-quarters of global GDP,” BNEF said.
But there are clouds between what would otherwise be good news. It accounted for 14% of new emissions last year, led by coal, which jumped 8.5% from the previous year to a record 9,600 TWh. This caused carbon dioxide emissions from the energy sector to increase by 7% from the previous year.
However, this figure of 14% of new capacity from fossil fuels is the lowest level ever seen, according to BNEF. About 13 GW of coal capacity was added last year, down from 52 GW in 2019 and 82 GW in 2012.
“It’s been a big and big year, for the best and the worst reasons,” Ethan Zindler, head of America at BNEF, said in a statement reported by Utility Dive. “Renovation has grown rapidly, but the return of coal and the fact that countries – including those committed to achieving zero emissions – continue to build coal is very worrying.”
BNEF said three factors led to the increase in coal power last year: a 5.6 percent increase in global electricity production due to the recovery of the global economy, less electricity production due to drought, and higher natural gas prices. In terms of coal capacity growth, China increased by 9%, India increased by 16%, while the United States increased by 14% compared to the previous year. China’s power industry accounted for 36% of carbon emissions from energy production last year, followed by the United States at 12% and India at 8%.
Energy consumption could rise again this year as European countries seek to offset drought and high gas prices by restoring coal-fired power plants. plants into service or delay plans to retire the coal industry, BNEF said. Half of the countries that pledged at the UN Climate Change Conference in 2021 to phase out coal were produced last year.
The US & Solar Power
The annual solar report from Berkeley Lab is also out this week. He said the United States added more than 12. Read also : NREL-led breakthrough pushes perovskite cell to greater stability, efficiency.5 gigawatts of new capacity last year, bringing the total installed capacity to more than 50 gigawatts, with Texas responsible for about a third of that increase. Combined with residential and other distributed solar infrastructure, solar alone accounted for 45% of new capacity added to the grid last year.
According to ArsTechnica, the average cost of building electricity in the United States today is $1.35 per watt. The standard cost of solar power is falling faster than the cost of construction. In the US it is now $33 per MWh, with some PPAs coming in at $20 per MWh. Inflationary law could reduce that amount to about $27 per MWh or less.
IRA can interrupt a trend in the industry. Previously the only way to claim tax credit for battery storage was to combine it with a renewable energy installation. Now the vertical battery system is eligible, which can lead to the construction of many of them.
The Department of Energy reports that the cost of solar power competes with “the cost of burning oil in gas-fired engines.” In short, ArsTechnica says, it could potentially be more economical to not use the gas generator and use the money spent on oil to install a solar farm instead. so.
Prior to the passage of the IRA, the DOE was saying it expected the amount of new solar energy to triple by 2030 and increase rapidly from there. But now he says the new incentives in the IRA “could lead to even more pushback.”
All this extra solar will change “business as usual” for grid operators. Solar power will not be forced off the grid at midday on sunny days, Ars added. This means that the value of sunlight will decrease in some places as the generation starts to exceed. This, in turn, will cause the batteries – both personal and grid-scale – that are charged during these periods of excess as they drop in the value of the solar roof. And these changes can be felt before the decade is out.
The Forest For The Trees
All of these DOE solar projections are subject to finding a place to put all of these new solar farms. One of the biggest costs of any new energy infrastructure is connecting it to the grid. Read also : How much solar energy is produced in the us ?. Solar developers can save a lot of money by building a new solar farm where the grid connection is already in place.
Charlotte County in south central Virginia has several transmission lines crossing it. There are plans to tap those resources to accommodate the Randolph Solar Project, a 4,500-acre project that will require the removal of another 3,500 acres of forest during construction. At least 5 other solar areas are planned for them as well. When completed, they will be one of the largest solar installations east of the Rockies.
Recently, local resident P.K. Pettus spoke to the New York Times about solar projects. After Virginia passed a law in 2020 requiring the phase-out of fossil fuels from the electricity sector by 2050, Pettus said, “I’m very excited to see the light of day on parking lots, solar on rooftops, solar on big box stores. I never dreamed it would involve deforestation and identification in a place I care so much about.”
Environmentalists and agricultural activists argue that solar development drives away valuable forests and farmland. They believe that solar farms should be built on land that has already been developed or on contaminated land such as abandoned industrial sites and landfills. Some have warned that the Chesapeake Bay conservation plan, which has been in the works for decades, could be derailed by the loss of large tracts of forest land.
Pettus fears the Randolph project and other large solar farms in the area will send soil and stormwater into Roanoke Creek, which includes several wetlands and eventually drains into the Roanoke River. Runoff from forested slopes can harm water quality and aquatic life, she said.
“It’s disappointing on our part to see the situation get worse,” said Judy Dunscomb, a senior professional in the field. they’re trying to push through these big projects on the one hand and local governments are increasingly concerned about the impact of these projects.”
The United States Department of Energy says that installing solar panels on the roofs of houses and car parks can cover up to 80% of the country’s electricity needs. And while that may be true, there are fewer incentives for such installations and the cost of these systems per watt is much higher than for scaled-down solar. They are also not connected to the grid but offer the promise of supporting more resilient, more diverse types of microgrids.
Dominion Energy is planning to develop a solar farm in southwest Virginia on a hill that has been cracked by coal. Jobs like this have found a sweet spot, says the NY Times. They are big enough to understand the economic scale, which is on a country that is already damaged, and they can develop the economy of the region that needs economic help.
More of these former industrial sites are found on top of landfills, for example, but are often located far from transmission lines. And the surface of such sites can be weak, making construction complicated and expensive. Almost the worst thing that could happen to nature is for one of its best friends – solar power – to be seen as a bad neighbor that no one wants around.
The inflation-reducing bill will charge electric utilities across the United States. The main task is not to build them. The main task is to find out how to place them in places where they will have the support of the community and commit themselves to cooperation.
States will also adjust their interest in attracting high-quality workers. In Virginia, Amazon, Google, and Microsoft are committed to renewable energy, but together they use up to two gigawatts of electricity, about one-sixth of the state’s electricity consumption. If Virginia wants the benefits that employers can bring, it will need to figure out how to meet their renewable energy needs or look elsewhere.
It’s a delicate dance, and in the end it’s impossible to make everyone happy. The key is deciding what role carbon reduction should play. Because unless the Earth stops overheating, about three-quarters of people may disappear from the face of the earth by the end of this century. It’s a matter of preference, but that doesn’t mean the process won’t be boring.
