90 Alternative Power Source Proposals

From Greener Charcoal to Artificial Photosynthesis:

With more and more people becoming conscious of their energy consumption, many keynote speakers and inventors have focused their attention to the promotion of alternative power source proposals.

While solar and hydro power are two of the more commonly used, sustainable alternatives to fossil fuels, there are many new technologies and products by which eco-friendly power is being derived.

Plant-based fuel sources are being examined more extensively, as there have been breakthroughs in various extraction methods poised to remove a viable amount of energy from the foliage without leaving a lasting impact on the ecosystem. Bio-fuel and bio-waste are becoming more prevalent to power everything from cars and planes to electronics. Furthermore, scientists have been experimenting with various bacterial sources which can turn something traditionally seen as a negative product into a positively productive commodity.
