Tesla's new Solar Roof costs less than a new roof plus solar panels

Tesla has launched the third iteration of its solar roof tile for residential home use. On balance, the Solar Roof provides more energy generation than a similarly sized roof retrofitted with traditional tiles.

Renewable power capacity to grow by 50% in next five years

A new forecast finds that the world’s total renewable-based power capacity will grow by 50 per cent between 2019 and 2024. This is driven by cost reductions and concerted government policy efforts.

Europe's largest floating solar plant opens in France

The most powerful floating solar PV plant in Europe was inaugurated in southern France on Friday (18 October), marking another milestone in the development of solar energy.

UK renewables out-generate fossil fuels for an entire quarter

Renewables produced 29.5 TeraWatt-hours in July, August, and September, while fossil fuels only produced 29.1 TW-hr and that less than 1% of the UK's electricity came from coal during the quarter.

Wind meets Denmark's 100% power demand on Sep 15

The strong winds spurred production from wind turbines and helped supply 130% of the country's electricity demand from midnight to midnight last Sunday. The excess power was sold abroad.

Materials that can revolutionize solar energy

Researchers at Columbia University, U.S. have developed a way to harness more power from singlet fission to increase the efficiency of solar cells, providing a tool to help push forward the development of next-generation devices.

Scotland produced enough wind energy for double its homes

In the first half of 2019, Scottish wind generated enough electricity to power the equivalent of 4.47 million homes, almost double the number of homes there.

Water and green energy produced by a single device

The scientists adapted a solar panel that not only generated power, but used some of the heat energy to distill and purify sea water. The idea could make a major difference in sunny climates with limited water supplies.

US renewable capacity surpasses coal power for first time

A new report shows there was more biomass, geothermal, hydropower, solar and wind capacity installed on the US grid in April 2019 than plants set up to burn the fossil fuel.

Renewable energy: the global transition, explained in 12 charts

The world’s governments urgently need to bear down on heating and transportation, where most of the energy is being consumed. Energy systems need to be rapidly electrified and integrated.

Largest offshore wind farm kicks into operations in the UK

Hornsea One officially commenced operations this month. The project is the first in the world with a capacity of over 1GW, double the size of the current world’s largest.

Exotic matter uncovered in the sun's atmosphere

The new research has shed new light on the exotic but poorly understood 'fourth state of matter,' known as plasma, which could hold the key to developing safe, clean and efficient nuclear energy generators on Earth.

Breakthrough in new material to harness solar power

Physicists are pushing the performance of solar cells to levels never before reached. The ultra-high efficiency material called a tandem perovskite solar cell is being developed to help solve the world energy crisis.

Five EU countries call for 100% renewable energy by 2050

Luxembourg, Austria, Ireland, Lithuanian, Spain and Finland have joined in a call to a 100% renewable energy system, which includes heating, cooling, transport and other drains on power.

China Plans a Space-Based Solar Power

China will test the idea of a space-based solar power station that would capture the sun’s energy that never makes it to the planet and use laser beams to send the energy back to Earth. NASA has abandoned this idea decades ago.
