Solar power converts sunlight into electricity directly using photovoltaics or indirectly using concentrated solar power. Concentrated solar power uses lenses or mirrors to focus sunlight into a small beam. In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of electrodes in a conducting solution. While regular electricity must be paid for indirectly from power plants, solar power provides access straight from the sun and is often more cost-effective than fossil fuel options according to the World Economic Forum. China is currently the largest producer and consumer of solar energy in the world, with its solar capacity expected to double to 370GW by 2024. Solar power prices have dropped dramatically over the past decade and are
