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
