T he Renewable energy resources

Climate change Since Industrial Revolution in 1765: - CO2 From 280 PPM by volume to 360 PPM by volume.- Methane has doubled. In the past 100 years, levels of nitrogen oxide have risen about 15%. Next century expectation :Carbon dioxide approximately 600 PPM by volume.
