One of our biggest assets is the Sun. And we could do a lot more to put its energy to better use. Fossil fuel will run out, the Sun’s energy wont (it will, in about 5 billion years, so not quite the time to worry yet) .
Countries, world over, are increasingly turning to Solar power – a total of 161 countries now have renewable energy policies in place, and 172 have renewable energy targets (Renewables 2020 Global Status Report, REN21). Solar energy (and wind energy) have become mainstream electricity sources, as they are proving to be cost efficient as well as better for the environment (as compared to fossil fuel power plants).
