nonrenewable for the majority of our energy.
4. Coal
Advantages Disadvantages

• Currently inexpensive to mine causes acid rain
• Reliable and able to generate • Mining can be dangerous
large amounts of power • Eventually, the coal supply will
run out
6. Oil (Petroleum)
Advantages Disadvantages
• Good fuel for vehicles • High carbon dioxide emissions
• Economical to produce • Found in limited areas
• Easy to transport • Supply may be used up soon
• Environmental impact
through drilling and
transporting
7. Natural Gas
Advantages Disadvantages
• Widely available • Unavailable in many areas
• Cleanest burning fossil fuel • Still pollutes some
• Pipelines impact environment
8. Nuclear
Advantages Disadvantages
• No greenhouse gases • Although not much waste is
• Produces huge amounts of produced, it is very, very
energy from small amounts of dangerous.
fuel. It must be sealed up and
• Produces small amounts of buried for many years to allow
waste. the radioactivity to die away.
• Nuclear power is reliable. • Nuclear power is reliable, but a
lot of money has to be spent on
safety – if it does go wrong, a
nuclear accident can be a
major disaster.
