In an Integrated Resource Plan released for public comment earlier this month, the Tennessee Valley Authority pulled the plug on its 1,260-megawatt Bellefonte Unit 1 nuclear plant, a partially complete project that has been under construction since 1974.

Restorative farming practices and emerging products built from carbon-negative plastics could create opportunities for major carbon pollution producers to take responsibility for their historical emissions, even as they work to reduce their future greenhouse gas production.

Energy efficiency is already disrupting utility business models in the United States, with 40 years of electricity end use data pointing to a 25-year drop in consumption.

The White House may be balancing an impending rejection of the controversial Keystone XL pipeline with a quiet endorsement of oil and gas drilling in the Alaskan Arctic, analyst Deborah Lawrence suggested in a post this week on The Energy Collective.

The news that renewable energy producers added 103 gigawatts (103 billion watts) of new capacity in 2014 shows the world may be finally emerging from “the clean energy stagnation,” analyst Jesse Jenkins writes on The Energy Collective.

In what writer Edward Dodge describes as a “rare admission for a Chinese official,” a leading weather scientist told Xinhua last week that climate change poses a serious threat to the country.

Solar panels on California’s roofs could produce 4.8 to 6.5 times as much electricity as the state consumed in 2011, according to a new study in the journal Nature Climate Change.

U.S. energy subsidies declined and shifted focus from 2010 to 2013, and falling oil prices have cut into tax revenues in major oil-producing states, the Energy Information Administration reported last week in two separate releases.

While deep decarbonization scenarios depend on reducing carbon dioxide emissions per unit of economic activity by 4% to 10% per year, economies only managed to reduce that carbon intensity by 0.9% per year between 1990 and 2005.

With losses of €4.8 billion (US$5.4 billion) this year and €500 billion last, and sales expected to drop 5% in 2015, French nuclear giant Areva “has ten tons of financial debt on a five-ton truck,” blogger Dan Yurman reports on The Energy Collective this week.
