Getting solar panels installed on your home can decrease your carbon footprint, but it can be expensive. One way to lower that cost is by selling some of the excess power generated by those panels back to the grid. That's called net metering. GPB's Peter Biello spoke with Dr. Marilyn Brown, a professor of sustainable systems in the School of Public Policy at Georgia Tech about the policy.

India, on track to become the world's most populous country, gets about 70% of its electricity from coal. But the government is aggressively investing in renewable energy — particularly solar.

Renewable energy sources covered Greece's electricity demands for about five hours last Friday, the operator of the country's power grid said.

The slowdown is caused in part by an ongoing federal investigation into alleged tariff evasion by foreign solar cell manufacturers.

State regulators are set to vote next week on Georgia Power’s long-term plan that environmental and clean energy advocates say falls short of renewable energy goals and of responsibly closing coal-fired power plants.

Alderman Nick Palumbo says Savannah is poised to become Georgia's largest municipal provider of solar energy.

California broke its record for renewable energy when solar and wind provided enough to meet all consumer demand. At the time, natural gas power plants were still on, a necessity for the grid.

It’s getting more urgent than ever to switch from fossil fuels to renewable energy to minimize the devastation of climate change, according to a landmark report last week. And solar panels are cheaper than ever. But for Georgia Power customers, it’s not quite that simple. Most still need to get some of their electricity from the utility, and a program that made that mix of power sources affordable has just filled up.

The Southern Alliance for Clean Energy has mapped out ways for Georgia Power's parent company to switch to renewable energy by 2035.

This year, China pledged to go carbon-neutral by 2060. It has invested heavily in solar, wind and nuclear energy. Still, coal-fired heavy industry made up 37% of its economic activity last year.

By allowing individuals to buy solar equipment in bulk, programs in Atlanta and Savannah aim to help make renewable energy affordable.

For years, the Navy has objected to offshore wind farms on the California coast. The Biden administration announced a deal for new projects, crucial to achieving its climate change policy.

In 2020, renewable power was "the only energy source for which demand increased ... while consumption of all other fuels declined," the International Energy Agency says.

The companies face an existential threat as more governments and businesses move to tackle climate change. So a growing number have their own plans to decarbonize, by creating renewable gas.

Some prominent Republicans have blamed wind and solar power for the blackouts in the storm-stricken state. But the truth is that every source of generation fell short.
