Just like he said he would, President Obama has ordered the federal government to work toward getting 20 percent of its electricity from renewable sources by 2020.
Another study finds that wind power is an effective CO2 emissions reducer, even when “cycling” of fossil-fuel plants is taken into account.
Wind has grown faster than forecast, solar has become cheaper than anyone imagined – recent history tells us that we can decarbonize and beat climate change.
Factoring in climate change costs and other health impacts, researchers find wind the best choice for new generation, with solar PV gaining as well.
Swedish researchers say bioenergy with carbon capture and storage can turn around the global warming trend eventually even if we miss near-term targets.
Along with limiting CO2 emissions from power plants, President Obama says he’ll push for additional renewable energy, including more big projects on public lands.
A Michigan prof argues for policies that clean up the systems that produce motor vehicle fuel, whatever form it takes, instead of pushing EVs.
Some say replacing coal with natural gas – and perhaps nuclear power – can get us to an all-renewable energy future. But is there time?
New technology from a Nova Scotia startup increases the amount of carbon sequestered in concrete.
Fossil fuel consumption must decline and carbon emissions must begin to fall by the end of the decade, that’s all there is to it.
