Pros and cons of non-renewable energy resourcesDifferent methods of generating electricity have advantages and disadvantages. Advantages of renewable energy sourcesPower stations fuelled by fossil fuels or nuclear fuels are reliable sources of energy. This means they can provide power whenever it is needed. However, their start-up times vary according to the type of fuel used. This list shows the start-up times for different types of fuel going from the shortest to the longest.
Nuclear power stations and coal-fired power stations usually provide 'base load' electricity - they are run all the time because they take the longest time to start up. Oil-fired and gas-fired power stations are often used to provide extra electricity at peak times, because they take the least time to start up. Disadvantages of non-renewable energy resourcesFossil fuels took millions of years to form in the Earth's crust, and can never be replaced once they have been used. If we keep using these fuels they will eventually run out. We call fuels that will run out 'non-renewable'. Oil and gas will be the first to run out and then coal. When fossil fuels burn, they release carbon dioxide into the atmosphere. Research shows that a major contributor to the green-house effect and global warming is our overuse and burning of fossil fuels. Coal and gas also release sulphur dioxide gas when they are burned. Sulphur dioxide can cause breathing problems for living creatures and is also a major part of acid rain. The use and impact of fossil fuels The fuel for nuclear power stations is relatively cheap, but the power stations themselves are expensive to build. It is also very expensive to dismantle old nuclear power stations and to store their radioactive waste, which is a dangerous health hazard.

What are the advantages and disadvantages of nonAdvantages of Non-Renewable Energy
Huge profits can be generated in the mining of coal, selling of oil or the construction of natural gas pipelines. These resources are easy to use whether in a home or anywhere else. Consumers can find non-renewable resources at a very cost-effective price.
What are the disadvantages of nonrenewable energy?Disadvantages of non-renewable energy. It produces greenhouse gases.. Its by products cause damage to the environment.. Once exhausted they are not easily replenished.. Rising cost.. Its residual products are generally non-biodegradable.. Its products pose potential threat to human health.. Responsible for acid rain.. What are the advantages of nonrenewable energy. Resources?The main advantages of non-renewable energies are that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles. Non-renewable energy is cost-effective and easier to produce and use. Non-renewable resources are high in energy.
