The following text will move on with the development of sustainable energy today and tomorrow. | |||
Technologies for using sustainable energies are getting encouraged and the politicians and a lot of people invest in this kind of technology. In 2005 about 5.8 billion Euros were invested, already 23 % more than in 2006 (Hennicke, Peter: Erneuerbare Energien, München 2007). Also some countries pass renewable energy laws. In Spain all new buildings are committed to build solar collectors for creating their own warm water. Especially because of the higher oil prices, the politicians try to support people in using sustainable energy (Hennicke, Peter: Erneuerbare Energien, München 2007). | |||
Germany, the USA and China are the three countries with the most systems for sustainable energy. China already is the country with the most solar systems for warm water. In comparison with Germany where most of the sustainable energies come from windmill-powered plants (Hennicke, Peter: Erneuerbare Energien, München 2007). How the progress will go on in the future is a question of the world climate policy and of the price of other fossil fuels; oil etc (Hennicke, Peter: Erneuerbare Energien, München 2007). But even oil companies like „Shell“ estimate a considerable increase of using sustainable energy in the second half of this century (Hennicke, Peter: Erneuerbare Energien, München 2007). The „International Energy Agency“ (IEA) mentioned two years ago that already in 2010 there will be barley enough oil for the whole world. | |||
The IEA is a company for research, development, market launch and application from energy technologies. Because of the oil crisis 1974, sixteen countries align with each other to override the crisis (http://www.iea.org/ (30.12.2009)). | |||
The „International Energy Agency“ thinks if there will be a cost cutting for the technology of sustainable energy more people would build it and use it. In their opinion it is also important to really have the will to decrease the CO²-emissioN (Hennicke, Peter: Erneuerbare Energien, München 2007). In 2007 in Germany the emissions were 861 Million tonne, at least 56 Million tonne less than 2001 (http://www.iwr.de/ {30.12.2009}). One point of the decreasing CO²-emission is probably because in Germany already big and influential energy companies have invested in the sustainable energy systems. „E.ON“ wants to build offshore wind-mill plants for 500 MW until 2011 (Hennicke, Peter: Erneuerbare Energien, München 2007). „EnBW“ will create the first energy system from waves. The commissioning date will be 2010 / 2011. By then they plan to get electricity for at least 120 households (http://www.enbw.com/ (30.12.2009)). | |||
So companies, the politicians and most of the people know the problem and know how important it is to use sustainable energy. The need of supporting and developing sustainable energy systems is known world-wide. But there are still big and important countries like India where most of the people live in unsustainable areas. So it is the job of all the other countries to clarify the importance of sustainable living. | |||
