Renewable energy, facts and information

At least 29 U.S. states have set renewable portfolio standards—policies that mandate a certain percentage of energy from renewable sources, COVID-19 is making us rethink energy and emissions.

Setting the Record Straight About Renewable Energy

One study estimates that renewable energy sources typically emit about 50g or less of CO2 emissions per kWh over their lifetime, compared to about 1000 g CO2/kWh for coal and 475 g CO2/kWh for natural gas. Most of the lifecycle emissions from fossil generators occur from fuel combustion, but also come from raw materials extraction, construction

The race to zero emissions, and why the world depends on it

A key element is powering economies with clean energy, replacing polluting coal - and gas and oil-fired power stations - with renewable energy sources, such as wind or solar farms. This would dramatically reduce carbon emissions. Plus, renewable energy is now not only cleaner, but often cheaper than fossil fuels.

Sources of Greenhouse Gas Emissions | US EPA

The remaining generation in 2022 came from non-fossil fuel sources, including nuclear (19%) and renewable energy sources (21%), which include hydroelectricity, biomass, wind, and solar. 1 Most of these non-fossil sources, such as nuclear, hydroelectric, wind, and solar, are non-emitting.

Global Energy Review: CO2 Emissions in 2021 – Analysis

Global CO 2 emissions from energy combustion and industrial processes1 rebounded in 2021 to reach their highest ever annual level. A 6% increase from 2020 pushed emissions to 36.3 gigatonnes (Gt), an estimate based on the IEA''s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy,
