Renewable energy comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat. Fossil fuel-based power systems have negative environmental impacts like greenhouse gas emissions, climate change, and depletion of the ozone layer. Global warming occurs as greenhouse gas levels rise due to fossil fuel usage, increasing average temperatures and affecting rainfall patterns, sea levels, and human health. Renewable energy sources include solar thermal, solar PV, wind, hydro, biomass, and waves, while distributed energy systems can provide generation from multiple small, dispersed units.

Introduction
• What is Renewable Energy?
• Renewable energy is energy generated from natural resources—such as
sunlight, wind, rain, tides and geothermal heat—which are renewable
(naturally replenished).
• Renewable energy technologies range from solar power, wind power,
hydroelectricity/micro hydro, biomass and bio fuels for transportation.

Power Generation by Non Conventional Energy Sources
Global warming:
1. Due to emissions from the fossil fuel based systems, the green house
gases in the atmosphere increases.
2. As a result, the average temperature of the earth is becoming higher.
Effects of Global warming:
1. changes in rainfall patterns
2. rise in sea level
3. impacts on human health
