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.
But the US energy demand saw an increase of nearly 3 percent, which is roughly double the amount of additional solar generation. Should electric use continue to grow at a similar pace, renewable production will have to continue to grow dramatically for a few years before it can simply cover the added demand.
Twenty-three countries of the mentioned 30 countries, about 76.7%, have no reported academic solar energy research yet.
