Sunlight is booming as a new source of power. Combined with batteries to make it a consistent all-day source, sunlight has the potential to replace the use of fossil fuels (CO2) that trap heat in the atmosphere and cause climate change.
This change is happening on a scale that could be effective in saving life on Earth. Worldwide, solar panels now occupy an area about half the size of Wales, and this year, solar panels will provide the world with 6% of its electricity.
Recently, worldwide solar capacity has doubled every three years. Experts estimate that by the 2040s, solar will be the world’s largest and least expensive source of power and energy.
