Renewable energy sources may eventually render fossil fuels irrelevant in energy generation, but when will the switch between the two energy sources occur? It's a question that fosters much debate among policymakers, environmental advocates, and financial analysts. For its part, ExxonMobil believes fossil fuels—notably including... Exxon says coal will endure; other analyses beg to differ
Renewable energy sources may eventually render fossil fuels irrelevant in energy generation, but when will the switch between the two energy sources occur? It's a question that fosters much debate among policymakers, environmental advocates, and financial analysts. For its part, ExxonMobil believes fossil fuels—notably including... 
The winds of change are blowing harder in the U.K. The price of energy generated by offshore wind farms has been falling steadily, and ahead of schedule too. Costs have fallen 32 percent since 2012, bringing them below a target of £100 per megawatt-hour previously set by the U.K. government and utilities. DON'T MISS: When lauding renewables... 
Islands can be excellent places to promote clean energy. Because they are typically disconnected from both mainland grid infrastructure and sources of fossil fuels, it is easier for alternative sources of energy to gain a foothold. In fact, the cost of importing coal or oil to fuel power plants or vehicles can make fossil fuels vastly more... 
From the perspective of both renewable-energy advocates and electric utilities, grid-scale energy storage offers many potential benefits. By storing energy in battery packs for later use, energy storage can make intermittent renewable sources like solar and wind into more reliable forms of power. It also helps utilities "balance" the gird by... 
While renewable-energy use has grown substantially over the last few years, the regulatory environment remains volatile. Some states have worked hard to stimulate renewable energy, supporting infrastructure projects and offering incentives to consumers who install home solar arrays. But others have tried to restrict renewable energy, often at the... 
The news on the renewable energy front continues to be good, with the costs of wind and solar generation falling steadily. By some measures, large-scale renewable energy is now cost-competitive (or close) with the most efficient natural-gas electric plants. Moreover, the amounts of clean generating capacity installed continue to rise, both in... 
While modern electric cars have only been available in large numbers for a few years, electric trains have been commonplace for some time. As with electric cars, the source of the electricity used to power these trains impacts their overall carbon footprint. The cleaner an energy source, the cleaner the vehicles it powers.

Despite a recent downturn, the Chinese government is moving full-speed ahead to invest heavily in renewable energy. The country's national regulators have already promoted renewable energy as a possible cure for the country's notoriously-bad air pollution. But China has placed more emphasis on renewable power in its latest five-year economic plan... 
President-elect Donald Trump's choice of Oklahoma attorney general Scott Pruitt to lead the Environmental Protection Agency (EPA) indicates that his administration will pursue radically different energy policies from its predecessor's. Pruitt is a climate-science denier, and has sued the agency he is being asked to lead multiple times. He has... 
Renewable-energy growth has accelerated in 2016, but this may go down as a milestone year for one renewable-energy source in particular. Together, all renewable-energy sources are expected to account for 8 percent of U.S. electricity-generation capacity in 2017, according to the Department of Energy, and solar energy is responsible for most of...
