U.S. Solar Capacity Has Grown 28,500% Since 2008

  • U.S. solar power capacity has jumped by 28,500% since 2008.
  • Supportive policies, like the Inflation Reduction Act, could provide another boost for the industry.
  • With the cost of solar energy technology falling significantly in recent years, investors are seeing lower set-up costs and a greater return on their investments.
Solar Capacity

The U.S. has plans to expand its solar energy market exponentially in support of its optimistic climate change policies. The country has already established several widescale solar projects, and with the introduction of the recent Inflation Reduction Act (IRA), renewable energy companies are being provided with the funding and tax cuts needed to encourage more rapid expansion of a variety of green energy projects. With a massive solar pipeline over the next few years, the U.S. will soon become a regional solar power hub. 

The solar power capacity in the U.S. has grown from just 0.34 GW in 2008 to an estimated 97.2 gigawatts (GW) today, providing enough energy to power 18 million homes. However, at present, just 3 percent of the country’s electricity comes from solar photovoltaics (PV) and concentrating solar-thermal power (CSP), demonstrating the potential to expand the industry much further. 

With the cost of solar energy technology falling significantly in recent years – for example, PV panel prices have dropped by nearly 70 percent – investors are seeing lower set-up costs and a greater return on their investments. Solar power has become highly competitive with fossil fuel projects, particularly thanks to government incentives across several countries to establish renewable energy projects. The U.S. is a prime location for the expansion of the solar energy industry, with estimates suggesting that installing PV panels on around 22,000 square miles of land would provide enough electricity to power the entire United States. In addition, solar panels can be installed on rooftops to reduce land use. 

The U.S. solar energy industry has supported job creation countrywide, with solar jobs increasing by 167 percent within the last decade. There are now over 250,000 solar workers in the U.S., a figure which is expected to continue growing as more solar energy projects come into operation. 

The solar energy pipeline in the U.S. is impressive, with producers moving beyond regions with the highest sun intensity, as many of the best solar resources are already occupied by existing projects. Operators are now looking to develop projects in areas such as the Southeast, Mid-Atlantic, Midwest and Northeast. New technologies, such as tracking systems that follow the sun across the sky, are helping producers increase their solar energy output, even in less sunny regions. The solar energy industry is evolving with the times, in a shift from traditional solar power projects, most recent large solar projects have included applications for battery storage – this is true for 95 percent of the pipeline in California. 

One major solar project is catching the world’s attention, the $1.5 billion Mammoth solar farm planned for northern Indiana. The development is expected to be the largest in the U.S., with Indiana and Israeli-based Doral Renewables LLC investing in a solar farm 1,000 times the size of a football stadium, at around 13,000 acres. Mammoth is expected to be carried out over three phases, with phase one commencing in October this year, and its completion planned for 2024. Approximately 2.85 million panels will be installed on the solar farm, enough to power around 250,000 homes. 

But it’s not been all clear sailing, as the developers have faced several obstacles to the construction of the solar farm. The state of Indiana and Doral Renewables have faced several lawsuits and anti-solar energy operations propaganda. Most of the land being converted to produce solar energy was previously farmland, in a region with a high concentration of agricultural activity. One woman, Connie Ehrlich, is spearheading the campaign against the development of the solar farm, stating: “We need to protect America’s farmland… Not only from being sacrificed for the inefficient, unreliable energy generation but from foreigners’ interest!” in a Facebook post. 

This is not the first time that the renewable energy industry has faced opposition to new projects, with solar developments in Ohio, Kentucky, and Nevada all having faced delays due to pushback from local communities. Ordinances that limit solar, wind, and other renewable energy project development have been passed in 31 states so far. Many farmers see the use of land for renewable energy developments as a threat to their livelihoods, and there are many environmentalists with ecological concerns.

But the opposition is not deterring green energy companies from proposing new developments, particularly following the announcement of greater government funding and tax cuts for new renewable energy projects in the U.S. Nick Cohen, CEO of Doral Renewables, said “It’s just throw spaghetti and see what sticks,” about developing new solar power projects. 

Despite a variety of obstacles facing solar energy project developers, the introduction of more favourable renewable energy policies by the Biden Administration in recent months has led to a flurry of proposals and investment in the U.S. solar industry. While not every development in the solar pipeline will be successful, the growing number of investors in the solar market will support the development of the United States as a regional solar energy hub over the next decade.

    It is easy to for US solar capacity to reach such an extraordinary growth rate when it is starting from near zero growth rates.

    And despite huge expenditure in the United States on renewables, they only account for 7% of US primary energy consumption compared with 81.8% for fossil fuels. In fact, only 3% of electricity is generated from solar energy compared with 40.6% from natural gas, 19.7% coal, 19.4% nuclear, 12.8% renewables (solar and wind), 6.7% hydro and 0.44% oil.

    It will take decades and an expenditure of trillions of dollars before solar energy overtakes coal or natural gas in electricity generation if ever.

    It will take perhaps a decade. Renewables are getting cheaper and more efficient by the year.

    Here are some quotes from the EIA:

    Increases in U.S. electricity generation in our forecast come almost entirely from solar and wind. We expect renewable sources will provide 22% of U.S. generation in 2022 and 24% in 2023, up from 20% in 2021.

    Natural gas fuels 38% of U.S. electricity generation in 2022, up from 37% in 2021, but we forecast it to fall back to 36% in 2023. Coal-fired electricity generation falls from 23% of the U.S. total last year to 20% in 2022 and 19% in 2023. Growing generation from renewable sources limits growth in natural gas-fired generation, and coal’s generation share declines because of the expected retirement of some coal-fired capacity.
