Alternative energy
Alternative energy is energy derived from sources that do not harm the environment or deplete the Earth's natural resources. Typical sources include
wind and
solar. Nuclear energy is usually excluded from this definition.

Future energy development
Future energy development, providing for the world's future energy needs, currently faces great challenges. These include an increasing
world population, demands for higher
standards of living, a need for less
pollution, a need to avert
global warming, and a possible end to
fossil fuels (see
Hubbert peak theory). Without energy, the world's entire industrialized infrastructure would collapse;
agriculture,
transportation,
waste collection,
information technology, communications and much of the prerequisites that a developed nation takes for granted. A shortage of the energy needed to sustain this infrastructure could lead to a
Malthusian catastrophe.
