Study Notes
Energy Scenario in India
- India is the sixth largest energy consumer in the world.
- The country's energy consumption is expected to increase in the near future.
- Fossil fuels are the largest energy source, providing around 76% of India's electricity.
- Hydroelectric power accounts for 22% of India's electricity, while nuclear power accounts for 2%.
- India's total energy consumption has increased approximately fourfold over the last three decades.
Coal in India
- India is the world's third largest coal producer, ranking behind the United States and China.
- Domestic production of coal meets approximately 95% of domestic demand.
- Coal consumption is expected to increase by 28% by 2010.
Oil in India
- Oil provides roughly 30% of India's energy.
- Domestic production of oil provides for only a third of India's oil demand.
- By 2010, roughly 75% of India's oil and gas needs will be met by imports.
- The government predicts that India will deplete its oil reserves by 2012.
Renewable Energy
- Renewable energy sources, such as wind, solar, small hydro, and biomass, are receiving increased attention.
- Replacing fossil fuels with fuels made from plant matter could save money and strengthen energy security.
- Renewable energy is plentiful, and the technologies are improving all the time.
- Renewable energy provides long-term sustainable development not only in agriculture but also in all other sectors.
Tidal Energy
- Tidal energy harnesses the power of ocean tides to generate electricity.
- This is done by constructing a barrage (barrier) across the sea to create a basin for storing water.
- During high tide, water flows from the sea to the tidal basin through a turbine, producing electricity.
- During low tide, water flows from the tidal basin to the sea through a turbine, again producing electricity.
Non-Renewable Natural Resources
- Non-renewable energy sources are those that will eventually run out.
- There are four major types of non-renewable resources: oil, natural gas, coal, and nuclear energy.
- Oil, natural gas, and coal are collectively called fossil fuels.
Oil Energy
- Crude oil is referred to as Liquid Petroleum and is used for gasoline, heating oil, and diesel fuel.
- Burning fossil fuels sends greenhouse gases into the atmosphere, trapping the sun's heat and contributing to global warming.
- Pollutants released into the air, soil, and water when fossil fuels are burned harm the environment and humans.
