But we cannot totally rely on solar energy. Alternative sources also give us the potential to develop localized sources of energy without reliance on a grid and also what about the places where we don't have enough sunlight.

A patch of algae or a patch of solar cells. While I'm not exactly sure of the numbers good solar cells can convert around 17% of the incoming light into electric energy while algae's conversion is less than 1%.(I'm not making that up I'm studying at a university where there research algal fuels). If you are talking about a major fuel source than by efficieny solar cells win out. Algae has the benefit of being able to create synthetic chemicals without relying on fossil fuels so the substrate. When it comes down to it there are only 3 types of renewable energyl; energy from the sun, heat the the center of the earth, and gravitational energy from the earth-moon/sun. Its good that a company can convert a waste stream ie; onion skins to a fuel source, but that can in no way provide a fraction of the power needed. Think about it this way, how much land would be required to power that onion plant with pv, vs how much land the onions are grown on. While its interesting to read stories about energy fromw weird sources like a couple of years ago when everyone was amazed you could run a car on waste oil from restaurants,(not that surprizing cause fry oil has the word oil in it) its not helpful. Solar can work it just needs to be heavily subsidized to compete with coal atleast for now. What is a more efficient use of land? A patch of algae or a patch of solar cells.
