  Nuclear power emits a relatively low amount of carbon dioxide (CO2). Greenhouse gas emissions are low, so nuclear power plants only make a relatively small contribution to global warming, an available technology that does not require much research and development. High power output with a single plant. Radioactive waste remains an unresolved issue. Waste from nuclear energy is extremely dangerous and must be carefully stored for thousands of years (10,000 years by the standards of the US Environmental Protection Agency). High Risk: Despite a generally high safety standard, accidents are still possible. Building a factory with 100% safety is impossible. There is always a small probability that something will go wrong. The consequences of an accident are absolutely devastating to both man and nature.

In the near future , some source energy like coal,oil or fossil fuel will be exhausted. So , there must have another source of energy for people to live . Now , a lot of scientists think about using three kinds of energy: Solar energy , water energy and water energy . In three kinds , people usually prefer solar energy than others . In my opinion , I'll will talk about advantages and also disadvantages of solar energy.

Firstly , solar energy is from the sun . It often rises about twelve hours a day so it's also convenient to use all day

Secondly , when you need a hot bath , just turn on the solar panel on the roof because it's absorb solar energy during the daylight time. Then enjoy it.

Finally , It's minimize the Carbon Dioxide , Sulfur Dioxide and other hamful gases from factories . It's also reduce waste of coal , oil , fossil fuel.

But it's expensive to buy a solar panel because it's exchange a lot of rare meatal like potassium , aluminum or berium.And if you don't use hot water after two - three hours , it will be cooler because it don't have any sun during the night time.

In conclusion , I think solar energy have more advantages than disvantages
