Solar

• advantages

1. Solar panels catch energy directly from the sun and convert it into electricity.

2. Solar energy produces no emissions.

3. Solar enables people to generate their own energy where they live: people can have their own solar panels, with batteries for calm days.

• disadvantages

1. The cost of the panels is still very high.

2. Clouds and darkness also cause solar panels to produce less energy, which requires one to have additional power sources (such as batteries) available.

Wind

• advantages

1. It works well on cloudy days.

2. Wind enables people to generate their own energy where they live: people can have their own windmills, with batteries for calm days.

• disadvantages

1. The turbines are both noisy and ugly.

2. If the wind doesn’t blow, the turbines don’t have the capacity to produce sufficient energy.

Nuclear

• advantages

1. Nuclear power produces vast amounts of electricity more cheaply than gas or coal, with no carbon emissions.

• disadvantages

1. Use of nuclear power declined due to accidents, concerns about nuclear waste storage and disposal, and high construction costs.
