Solar Energy: Difference between revisions

== Introduction ==

There are a lot of different ways to create energy, but because of the limited capabilities, it is important to use sustainable energy. Our earth gets more and more abuse, because of the globalisation, flying by plane, using cars etc., on the other hand the globalisation can help us to get new systems for using new ways for getting energy and to get all the materials for it. But the global warming and the accumulation of greenhouse gases in our atmosphere brings extreme weather events and rising sea levels (Curtis, Fred: Climate, Peak Oil, and Globalization: Contradictions of Natural Capital), just to name some of the consequences.   

== Globalisation = more energy ==

As previously stated, the world population has increasing energy demands, and more resources are needed to provide this energy. At the current rate of population growth, by 2050 there will be an estimated 9 billion people on earth (Geitmann, Sven: Erneuerbare Energien und alternative Kraftstoffe, Kremmen 2004), all needing energy. The amount of energy required per person is also increasing, as people seek greater independence, freedom and mobility – all factors which result in globalisation. For example the world’s fleet of cars actually grows faster than the human population does, and industrialisation continues to march on. However it is worth noting that energy consumption in industrial countries is disproportionate to that of developing nations. The industrial countries consume more than half of the world’s energy resources, despite constituting just one-seventh of the world population. For example, the USA accounts for 5% of the world population however they consume 26% the crude oil produced worldwide (Geitmann, Sven: Erneuerbare Energien und alternative Kraftstoffe, Kremmen 2004). And because of the progression of industrialisation in the less developed countries, combined with the fact that energy expenditure in the industrial nations is not regressing, new ways of creating energy must be developed.
