Solar energy is directly from the Sun by its heat and light. We collect it via solar cells, which convert the sun's energy to electricity, or harnesses its heat.

There are two main ways of generating energy from the sun. Photovoltaic (PV) and concentrating solar thermal (CST), also known as concentrating solar power (CSP) technologies.PV converts sunlight directly into electricity. These solar cells are usually found powering devices such as watches, sunglasses and backpacks, as well as providing power in remote areas.Solar thermal technology is large-scale by comparison. One big difference from PV is that solar thermal power plants generate electricity indirectly. Heat from the sun's rays is collected and used to heat a fluid. The steam produced from the heated fluid powers a generator that produces electricity. It's similar to the way fossil fuel-burning power plants work except the steam is produced by the collected heat rather than from the combustion of fossil fuels.

Damnit, wish I didn't skip science class so much :P

Anyway I think u can harness anti matter to produce energy which u can convert 2 electricity, so add that to a possible candidate. Also I guess if u can create mini black hole's (not considered fairy tal anymore in R and D) u can create electricity. It will be superthermal, tho.

Those 2 sources I think give u INFINITE heat circulation and thus u can have infinite elec, i am sure!
