• Conventional energy sources includes oil, gas and coal. These conventional sources are usually fossil fuels.
• Their use leads to increased greenhouse gas emissions and other environmental damage.

Advantages are:

• Cheap to produce large quantities of power
• Building power plants are easy and can be done near cities
• Readily available/convenient and hence price is lower.

Limitation are:

• Burning fossil fuels produce CO2 which in turn causes Global warming.
• Nuclear is danger
• Fossil fuel supply will decrease and price increases.
• Nuclear waste will remain toxic for many thousands of years
