With demand for energy rising rapidly in industrializing countries such as China and India, energy from fossil fuels will be an increasingly valuable resource for years to come. But fossil fuels such as petroleum and natural gas will not last forever.
Advances in nanotechnology, however, might help us make these precious fuels go further by increasing fuel efficiency. Nanotechnology could also contribute to the development of alternative sources of energy such as affordable solar and hydrogen fuel cells.
