A brand-new Tesla may be coming soon to your neighborhood. But it could be on top of your neighbors’ home, not parked in their driveway. Tesla Inc. TSLA, -1.10% Chief Executive Elon Musk on Friday unveiled the electric-car company’s new solar-paneled roofs and said he expects to be fitting more than 1,000 a week within short order.

Tesla has launched the third iteration of its solar roof tile for residential home use, which it officially detailed in a blog post on Friday and in a call with media. Tesla CEO Elon Musk kicked off the call with some explanatory remarks on the V3 Solar Roof, and then took a number of questions.

Tesla's Elon Musk promises battery and solar solutions for the many EV owners who can't charge their cars.

Solar power continues to set stunning new milestones in the renewable state of South Australia, reaching 80 per cent of total demand on Saturday and accounting for more than 70 per cent of demand over four hours in the middle of the day.

These homes could dramatically reduce the cost of solar energy for homeowners.

HONG KONG — The busy rush hour in Shenzhen, a new city of some 20 million people in Guangdong Province, is almost silent. Commuters whisper past on electric bikes and scooters or board one of Shenzhen’s fleet of electric buses and taxis, all part of the city’s pool of 90,000 new energy-efficient vehicles. It’s part of what Chinese city officials call “ecological civilization.”

LA's next source of energy: a massive solar panel and lithium battery array in the Mojave, operated by 8minute Solar Energy, and capable of supplying 6-7% of the city's energy budget, with four hours of nighttime use. It will cost an eye-poppingly low $0.03.3/kWh, cheaper than natural gas.

Natural gas is a behemoth in Pennsylvania in terms of production, consumption, and electricity generation. According to the U.S. Energy Information Administration, natural gas is the top form of energy consumption in the state, and about 40 percent of electricity in Pennsylvania is generated from natural gas, just behind nuclear energy. Nationwide, natural gas is the single largest share of electricity production.

California Governor Gavin Newsom signed into law last week financial protections for consumer investments in rooftop solar energy. The law, AB 1208 authored by Assemblymember Phil Ting (D-San Francisco), extends a prohibition on cities and counties taxing the energy generated by rooftop solar panels for use by homeowners and businesses.

Solar power may currently make up less than 2% of the world’s energy mix, but the outlook of solar company executives is, uh, sunny. “What’s important is new [energy] generation, and in the US, renewables are 70% of new generation. It’s game over,” said Tom Werner, CEO of SunPower, the California-based solar company, speaking at the Fortune Global Sustainability Forum on Thursday in Yunnan, China.

Solar energy added more capacity worldwide than any other form of power over the past 10 years, a report released Thursday reveals. The “Global Trends in Renewable Energy Investment 2019,” commissioned by the United Nations Environment’s economy division, paints a bright picture for the future of renewables. It reveals that, between 2010 and 2019, the world poured $2.6 trillion into clean energy and boosted capacity from 414 gigawatts to 1,650 gigawatts.

Securing enough energy to meet human needs is one of the greatest challenges society has ever faced. Previously reliable sources—oil, gas and coal—are degrading air quality, devastating land and ocean and altering the fragile balance of the global climate, through the release of CO2 and other greenhouse gases. Meanwhile, earth's rapidly industrializing population is projected to reach 10 billion by 2050. Clean alternatives are a matter of urgent necessity.

Solar power has become cheaper than grid electricity across China, a development that could boost the prospects of industrial and commercial solar, according to a new study.

After California passed first-of-its kind legislation mandating solar panels on all homes built starting in 2020, a new poll finds that people across the country want to see that policy go national.

Scientists may have found a pathway to designing interfaces of hybrid materials that are capable of turning light into electrical currents with high efficiency—a breakthrough that could potentially boost the performance of solar cells and slash their manufacturing costs.

Researchers say one invention could solve two problems for people lacking basic resources

Researchers have found a way to purify water and produce electricity from a single device powered by sunlight. The scientists adapted a solar panel that not only generated power, but used some of the heat energy to distil and purify sea water. They believe the idea could make a major difference in sunny climates with limited water supplies.

LightSail 2 just got a new dashboard

Puerto Rico has a plan to rebuild its energy grid and move to 100% renewable power by 2050. Many communities are working toward that themselves, without help from the government.
