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. Over those 15 years, US global warming emissions declined about 17 percent.

In Climate Talks, Plans to Keep Planet from Overheating Should Not Ignore Water

Circle of Blue

Carbon-reduction plans, if not well designed, can worsen water scarcity and pollution. Plans to reduce carbon emissions should take water into account. Some low-carbon energy options require significant amounts of water. But other low-carbon technologies do not tread as lightly. Carl Ganter/Circle of Blue.

Five Things the “Nuclear Bros” Don’t Want You to Know About Small Modular Reactors

Union of Concerned Scientists

SMRs are nuclear reactors that are “small” (defined as 300 megawatts of electrical power or less), can be largely assembled in a centralized facility, and would be installed in a modular fashion at power generation sites. What are SMRs? Some proposed SMRs are so tiny (20 megawatts or less) that they are called “micro” reactors.

What Should EPA Do After Repealing the Clean Power Plan?

Legal Planet

It attempted to move away from fossil fuels and toward zero-carbon sources like solar power to supply electricity. The production and transportation of oil and gas also cause significant environmental impacts, as does the use of enormous amounts of water for cooling the generators. The Plan was Obama’s signature climate policy.
