Vocabularyinaugurat - eingeweiht

2. Energy Development

-Fossil fuels: There are three main types of fossil fuels: coal, petroleum, and natural gas.

.Electricity from fossil fuel power plants produces more CO2-proportion into the atmosphere.

. Current governments subsidize renewable energies by an estimated $500 billion a year.

2. Energy development

-CO2 emissions boost the greenhouse effect, the consequence is a massive, global temperature increase.

- reduction of CO2-emission: hybrid engines

more renewable energies

installation of carbon filters in cars
