Small-scale nuclear plants can be strung together and might save utilities on capital costs. But critics question the efficiency and operating costs of small-scale nuclear plants.
A Duke Energy coal-ash facility accidentally poured 100,000 cubic feet of muck this week into the Dan River on the North Carolina-Virginia border, turning it gray. The EPA is likely to tighten disposal rules on coal ash, but it won't designate it 'hazardous.'
January's frigid 'polar vortex' may have cost the US economy as much as $5 billion. Meanwhile, consumers are cranking up furnaces and bracing for their February utility bills.
The deep freeze that grips much of the US brought the coldest temperatures in decades to parts of a shivering South. Usually mild, the region scrambles to shelter the homeless and help the stranded.
Large companies may be willing to pay for their emissions. Major companies including Walmart, American Electric Power and the five major oil companies have all incorporated carbon emission costs into their financial plans, according to a report by environmental data company CDP.
Nuclear power is currently the only carbon-free energy source that can provide base load electricity, Stepp writes, a characteristic crucial to reducing global greenhouse gas emissions and fighting climate change. Next-generation nuclear energy offers even more productive strategies for reducing carbon emissions.
Educators across the country are finding millions of dollars in savings through cheap and simple forms of renewable energy. Since 2003, one school district has cut more than $7 million in energy costs. That equates to 45 teaching positions.
