President Donald Trump has announced his intention to pull the United States from the Paris Climate Pact, but private companies and other entities are taking on the challenge of clean energy themselves. Goldwind Americas, a subsidiary of a leading Chinese wind-turbine manufacturer, continues to...

Elon Musk, habitually behind schedule, announced on May 10 that anyone can now preorder a Tesla Solar Roof—a roof made of shingles with built-in solar cells. Musk had previously said preorders would open in April, and promised the product would cost less than a conventional roof if you factor...

While the news headlines on President Donald Trump mostly address potential scandals, his administration has also lagged significantly in appointing top-level officials to run government agencies. Those that have been appointed often have an adversarial relationship to the missions of the agencies...

It's difficult to invest in renewable, alternative sources of energy when state-run oil pays the bills. And it's even harder for renewable energy when gasoline is all but free, courtesy of the same state. Now The Financial Times has taken a look at Russia's growing lag in embracing renewable energy...

It is widely accepted in the energy industry that U.S. coal production will fall as a percentage of the total electric grid mix. That has little to do with its high carbon footprint per kilowatt-hour generated; it is largely due to far greater supplies of much cheaper fracked natural gas. It is...

One of the major sources of carbon emissions is electricity generation. It's an issue that is becoming increasingly important in the automotive sphere, due to the slow rise of plug-in electric cars. So what would it take to eliminate carbon emissions entirely from making electricity? DON'T MISS...

If only we could all be as optimistic, and energetic, as Tesla CEO Elon Musk. Even as Tesla gears up for mass production of the Model 3 electric car and a hoped-for annual production rate of 500,000 total cars by next year, Musk has found time to place a high-profile bet on the renewable energy...

The new presidential administration seems poised to take a radically different approach to energy policy than its predecessor. That approach is founded on denial of accepted climate science, and an expressed desire to promote the fossil-fuel industry, including the so-called revival of coal. But...

Even before Elon Musk engineered Tesla's acquisition of SolarCity, the two companies were collaborating. SolarCity was already controlled by Musk, who believes its solar-energy business can be reinforced and complemented by Tesla's energy-storage business. Last year, Tesla announced a joint project...

Substantial growth in U.S. renewable-energy capacity will undoubtedly have a positive environmental impact. But the reduction in carbon emissions renewable-energy advocates aim to achieve does not exclude potential benefits to consumers. Because as renewable-energy generating capacity has expanded...

No matter how you measure it, 2016 was a major year for solar energy. More solar-generating capacity was added last year than either natural gas or wind, according to the U.S. Department of Energy. A study by investment bank and research firm Lazard found that utility-scale solar has now become the...

Mass adoption of electric cars and renewable energy could significantly decrease global consumption of fossil fuels. But does the established energy industry view these new developments as a threat? In a recent report, ExxonMobil said coal could continue to provide the majority of the world's...

Long a leader in the push to reduce vehicle emissions and switch to renewable energy, California marks another milestone this week. The last of three battery energy-storage sites will come online in Southern California, providing storage and buffering for unpredictable renewable energy. Together...

At first glance, renewable-energy sources like solar power and energy-storage battery packs seem like a logical match. Energy storage allows excess power collected by solar panels to be stored for later use, addressing the intermittent nature of solar power. It's a concept that has already won over...

If electric cars are adopted by mass-market buyers in years to come, that will lead over time to notably lower oil consumption. So what are oil companies doing to prepare for that possible outcome? Some continue to doubt whether electric cars will constitute a serious threat to their business in...

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...

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...

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...

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...

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...
