What are the Alternatives?
- Nuclear
- Not a renewable resource, but the time frames required (and apathy witnessed) to get to genuine alternatives mean demand for nuclear as a 'stop-gap' solution is set to rise.
- Hydro
- Hydro power is a highly-feasible solution already proven in many parts of the world. Norway now produces 99% of its electricity needs from Hydro power.
- Fuel Cells
- For both transportation needs and large-scale power generation, an increased awareness of the benefits of fuel cells is beginning to be witnessed, though benefits thus far have largely focused on environmental concerns.
- Wind
- Wind-generated power is a proven technology, but its adoption has been hampered by a previously higher cost versus fossil fuels, a situation that is destined to change.
- Liquefied Natural Gas
- Another interim measure en route to sustainable, renewable energy resources, LNGs could add 5-6mm bbl/d to world energy supplies in the next decade or so.
- Solar Power
- Solar fuel cells offer much promise, but are currently under-developed relative to other potential sources, and do not offer a current alternative.
- Bio-fuels
- Particularly bio-diesel and ethanol, these have the advantage of political backing, but are still expensive relative to current energy sources, and infrastructure build-out needed for widespread implementation could hamper progress.
- Coal
- Yet another fossil fuel with a finite supply, coal (and particularly so-called 'clean' coal) may provide a temporary solution to the coming energy supply crisis until renewable sources find their feet.
- Ocean
- Both thermal energy (from the sun heating the ocean) and mechanical energy (from tides) are good long-term possibilities for a renewable power source in the future.
