TECHNOLOGY AND ENVIRONMENT

	V. Ryan © 2002 - 2009

Our society and industry relies on large amounts of energy and the world is becoming increasingly dependent on fossil fuels (oil, gas, coal etc...). The industrialised nations of Western Europe and North America, China and India depend almost entirely on these fuels and the developing nations are also increasing their use.
It is understood that there is a direct link between the way we produce energy and damage caused by pollution. Finding cleaner and alternative ways of producing electricity / energy are now looked upon as being very important for the future of our planet.
ALTERNATIVE ENERGY SOURCES
Alternative Energy is a term used to describe sources of energy that occur naturally in the environment. For example, energy from the sun, the wind, movement of the oceans, etc.... Click on aspects in the index below to view examples.
