Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

The legislation committed nearly $400 billion to support, among other things, wind and solar power, battery storage, electric vehicles, and other clean energy technologies that will make a significant dent in US heat-trapping emissions. EN: We have already seen a great deal of progress.

Solar device generates electricity and desalinates water with no waste brine

Physics World

The device uses waste heat from the solar cell for desalination, thereby cooling the solar cell. It also produces no concentrated brine as waste, cutting its potential environmental impact. However, current desalination systems can be expensive and energy hungry, producing significant carbon emissions.

Minnesota: Will This Be the Year for a 100-Percent Carbon-Free Electricity Policy?

Union of Concerned Scientists

Those scenarios showed that the IRA would accelerate solar and wind deployment and reduce carbon emissions to 80 percent below 2005 levels by 2030. Municipal solid waste incineration adds to the pollution burdens borne by environmental justice communities. One area where the bill could do better?

Analysis: Is hydrogen the new oil?

A Greener Life

The Tokyo Olympics will be powered by a fuel with ambition – hydrogen. The Olympic village will be powered by hydrogen made at a solar power plant in the exclusion zone created after the Fukushima nuclear accident a decade ago. The Olympic flame is already burning it.

Analysis: Can Inner Mongolia reach peak carbon this decade?

A Greener Life

Yang Fuqiang thinks it is unreasonable to make energy-producing provinces such as Inner Mongolia solely responsible for cutting carbon emissions. If it benefits, it has to help cut carbon. There is huge potential for developing renewable energy in Inner Mongolia, which could be used to power other industries.

How Much Land Would it Require to Get Most of Our Electricity from Wind and Solar?

Union of Concerned Scientists

Acknowledging that the United States is a leading contributor to carbon emissions, the Biden administration has committed to cutting US emissions 50 to 52 percent below 2005 levels by 2030. By contrast, the land-use impacts of wind and solar projects tend to be short-term and reversible.
