Researchers have engineered a new perovskite solar cell that is stable and energy efficient.

Many people will see a dazzling eclipse this April, but these events are possible only because of the sizes and precise distances between Earth, the Moon and the Sun.

Now’s the time to get your hands on a pair of eclipse glasses in preparation for April’s display of celestial wonder.

Solar development isn’t always good for the land, but pairing it with agriculture can produce multiple benefits.

An online model enables users to calculate the least-cost strategy for a specific regional grid under various assumptions; outcomes vary widely from region to region.

When the Moon blocks the Sun during an eclipse, utility suppliers have to pull power from the grid to make up for gaps in solar energy.

Detroit’s plan to install solar panels in city neighborhoods may conflict with residents’ desires to see lower energy bills and more housing.

The work will help researchers tune surface properties of perovskites, a promising alternative and supplement to silicon, for more efficient photovoltaics.

Proposed reflectors would help provide clean energy when demand peaks near dawn and dusk.

You might hate winter, but at least you know what to expect every year. Other planets have wobbly axes that lead to wild, unpredictable seasons.
