How San Diego will feed its appetite for solar energy

San Diego is going to need lots of renewable energy if it’s going to nix planet-warming emissions from its economy in the coming decades, as it has pledged to do. One new study shows the county could technically generate what its people will need within its borders, but San Diego will probably need help from its neighbors.

Enter Imperial County. With a population 18 times smaller than San Diego, this 4.4 thousand square mile swath of land is rich in resources. It has first dibs on Colorado River water over entire western states, fueling a $2 billion agricultural industry that provides much of America’s winter vegetables.

MI universities may be developing the next big thing: clear solar panels

Silicon is king when it comes to solar panels, but the reign of that dark, opaque material could be near its end.

An unassuming stretch of windows on Michigan State University’s campus is poised to revolutionize solar energy, a fast-growing and increasingly prevalent source of power. The panes installed last year look like regular glass, but they harvest enough sunlight to power the lights in the Biomedical and Physical Sciences building’s atrium.

Solar energy can now be stored for up to 18 years, say scientists

Solar-powered electronics are one step closer to becoming an everyday part of our lives thanks to a “radical” new scientific breakthrough.

In 2017, scientists at a Swedish university created an energy system that makes it possible to capture and store solar energy for up to 18 years, releasing it as heat when needed.

Now the researchers have succeeded in getting the system to produce electricity by connecting it to a thermoelectric generator. Though still in its early stages, the concept developed at Chalmers University of Technology in Gothenberg could pave the way for self-charging electronics that use stored solar energy on demand.

Solar energy production increased by 20 percent in 2021

,

In 2021, Americans used 5% more energy than in 2020, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Last year, Americans used 97.3 quads (quadrillion BTU) of energy, which is 4.4 quads more than last year’s 92.9 quads – equivalent to a 5% increase.

Both 2020 and 2021 annual energy consumption totals are less than 2018 and 2019, where Americans used more than 100 quads per year.

Solar overtakes wind energy for first time in global rush for renewables

,

Solar power has overtaken wind for the first time, in the race to develop renewable energy capacity around the globe.

According to the International Renewable Energy Agency (IRENA), solar energy now accounts for 28% of the world’s renewable electricity generation capacity, just ahead of wind with 27%. This time last year, the two were evenly matched at 26% each.

The figures come from the latest Renewable Capacity Statistics report, released by the UAE-based organization on April 11.
