In 1956, solar power was priced at about $1,865 per watt and survived largely because spacecraft needed lightweight power. Decades later, prices fell below 50 cents per watt and solar became the cheapest new electricitySolar power once cost a staggering $1,865 per watt in inflation-adjusted terms. Today, solar panels can cost only a fraction of a dollar pe...
