RENEWABLE ENERGY TECHNOLOGIES
Energy is a fundamental to human systems, societies and survival. The future environmental health of Planet Earth depends directly on how much energy we consume and the form in which we consume it. People living in high currency countries (the economic North) use far more energy per head than their counterparts in poorer countries (the economic South). Every time the fridge door opens or the TV is switched on we are using energy, and add to such pollution problems as the greenhouse effect and acid deposition.
Energy matters are assuming a greater importance in our daily lives and careful consideration must be given not only to the various sources (fossil fuels, nuclear power, renewable energy) but also to developing more efficient ways of using energy.
Most of our electricity is produced by burning fossil fuels like coal, gas and oil. This process emits carbon dioxide, a principal greenhouse gas, and contributes significantly to global warming. Everyone agrees that we need to clean up our act. How to do it is a matter of great debate.
The government has advocated the use of nuclear power, and supporters thereof
say that it is a "clean technology" and does not contribute to the
greenhouse effect or acid rain.
