What are the alternatives to burning fossil fuels?

Moving toward to renewable energy is one of the many alternatives to burning fossil fuel.

Renewable energy (which includes solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, ocean currents, biomass, biofuel) can produce electricity more than enough to power our current and future lifestyle, without polluting the planet and causing global warming.

There are several other alternatives to burning fossil fuels that could also be considered. Nuclear Fission already produces a substantial share of the world's energy needs. Research continues into Nuclear Fusion and many are confident that it will soon be a technology we can harness with very small environmental impact.

The term Alternative Technologies in power generation also applies to other ways of improving the environmental impact of burning fossil fuel in power stations. A good example of this is Carbon Capture and Storage. Another is Trigeneration, which uses the heat from combustion to produce electricity AND provide heating and cooling for the building in which the facility is installed.

Hydrogen is being studied as a means of storing energy and producing power cleanly when required, but it can't be considered an energy source as we can't "mine" Hydrogen.

Waste To Energy is also being considered, but maybe that should not be considered "renewable" just on principle!

A key barrier to the widespread adoption to some of the renewable energy sources is intermittency: The sun only shines during the day, and sometimes the wind stops. Development of Storage technologies like molten salt, flywheels and batteries will greatly help!
