Solar accounted for 16% of California’s electricity sales in 2021

,

Solar became California’s biggest non-fossil fuel source of electricity sales in 2021, according to the latest data from the California Energy Commission.

In total, solar accounted for 15.9% of the state’s retail electricity sales, the highest among all renewable energy sources, followed by wind (11.5%) and geothermal (5.8%). In addition, 37.2% of the state’s retail electricity sales were from RPS-eligible (Renewables Portfolio Standard) sources in 2021, leading nuclear (10.8%) and large hydro (10.7%).

Together, non-fossil fuel sources contributed to about 59% of California’s retail electricity sales. This amount remained unchanged from 2020 despite the jump in renewables and drought-related declines in hydroelectric generation.

Wind and solar produced more than a fifth of the EU’s electricity last year, for the first time delivering more power than natural gas.

European solar and wind surpass gas power for the first time

Wind turbines and solar panels produced more than a fifth of the EU’s electricity last year, for the first time delivering more power than natural gas, a new report shows.

The analysis, from independent energy think tank Ember, indicates that wind and solar produced 22% of the EU’s electricity over the year, while gas generated 20%. The report further shows that the rise in renewable electricity generation helped to avoid €10 billion ($10.89 billion) in gas costs.

The use of coal, the most carbon-intense fossil fuel, rose by 1.5% over the year to generate 16% of European electricity—but this rise was short-lived, with thermal coal generation dropping markedly in the latter part of the year.

The off-grid solar sector has shown resilience in the face of pandemic-related challenges, with 70 million people gaining access to electricity from early 2020 to the end of 2021.

Off-grid solar continues to expand

Despite the pressure the pandemic has placed on supply chains and income levels, the number of people who source electricity from solar energy kits has continued to grow and has now reached 490 million.

According to the “Off-Grid Solar Market Trends Report 2022: State of The Sector” report – published by the World Bank’s Lighting Global, International Finance Corp. (IFC), GOGLA, Efficiency for Access Coalition, and Open Capital Advisors – the number of people who use solar energy kits had grown by 70 million by the end of 2021, up from 420 million in 2019.

The project will support the development of utility-scale solar resources & will boost the reliability of the bulk power system in AZ and CA.

US greenlights key solar line project to power California

The Ten West Link project is set to run 125 miles between the Delaney substation near Tonopah, Arizona, and the Colorado River substation in Blythe, California. It will be built next to an existing transmission line.

When CAISO evaluated the project, the grid operator found it would reduce costs for California ratepayers by gaining access to less expensive electricity in Arizona, the California Public Utilities Commission said in its November 2021 decision approving the project.

Among the project’s benefits, Delaney Colorado River Transmission expects it will reduce CAISO’s need to curtail renewable energy output on its system, according to the PUC.

Amazon agrees to 450 MW solar purchase in California with AES

Amazon.com Inc (NASDAQ:AMZN) has committed to buying electricity from 450 MW of solar parks to power its data centers in California under a deal with power distributor AES Corp (NYSE:AES).

The US e-commerce giant has sealed two power purchase agreements (PPAs) that will see it get renewable energy in the California Independent System Operator (CAISO) market. The power will be sourced from solar photovoltaic (PV) plants and 225 MW of battery storage projects with a four-hour duration.

The off-take deals were announced by AES on Thursday.

Concentrated solar-thermal power harnesses the sun's energy without photovoltaic panels, using mirrors to concentrate the sun's rays.

A different kind of solar power attracts attention

When you think of solar energy, you probably picture the photovoltaic panels that capture sunlight to be converted to electricity. But there are other ways to harness the sun’s power. One method attracting growing interest is called concentrated solar-thermal power, or CSP, which uses mirrors to reflect and concentrate the sun’s energy.

CSP has been held back by technical challenges and a shortage of funding and government incentives compared with other sources of renewable energy. But as the sense of urgency about replacing fossil fuels continues to grow, spurring demand for carbon-free energy, a number of increasingly well-funded entities are trying to improve the technology. Proponents say the heat that CSP systems produce and their storage capacity offer advantages over other renewables for generating grid-scale electricity and fueling various industrial processes.
