What makes solar energy revolutionary?

What makes solar energy revolutionary is the rate of growth which brought it to this just-beyond-the-marginal state.

What is solar energy & how does it work?

By far the most common solar energy technology, photovoltaics are an “additive” energy source that can be used on a single home’s rooftop or in a large farm producing thousands of megawatts of electricity—enough to power a midsize city. Instead of turning sunlight directly into electricity, concentrating solar turns it into heat.

How has solar energy changed the world?

Solar energy started its journey in niche markets, like most innovations, supplying electricity to applications where little alternatives existed in space and remote locations 22. Since then, cumulative investments and sales, driven by past policy, have made its cost come down by almost three orders of magnitude.

What is solar energy?

Solar energy is a form of carbon-free, renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use.

Why is solar power doubling every 3 years?

Installed capacity is doubling every three years. According to the International Solar Energy Society, solar power is on track to generate more electricity than all the world’s nuclear power plants in 2026, than its wind turbines in 2027, than its dams in 2028, its gas-fired power plants in 2030 and its coal-fired ones in 2032.

Why is solar power growing so fast?

It is one of the ironies of solar power that much of its growth has been driven by relatively unsunny countries, notably those of northern Europe, where there has been little demand for additional energy. The global south has a lot of empty land, better access to sunshine and much more unmet demand.
