What are the disadvantages of non-renewable energy?

Answer 1

Non-renewable energy means energy from sources that do not renew. Wind and sun renew, because they come back tomorrow. Coal and other fossil fuels are non-renewable.

Some disadvantages of non-renewable energy sources are that -

• they are non-renewable and fast depleting;
• they leave behind harmful by-products upon combustion, thereby causing a lot of pollution;
• mining of such fuels leads to irreversible damage to the adjoining environment;
• Fossil fuel pollutes the environment.
• It will eventually run out.
• It cannot be recycled.
• Prices for fossil fuels are rising, especially if the real cost of their carbon is included.
• Burning it produces carbon dioxide, a major cause of global warming.

  and it is running out and new energy sources need to be used such as nuclear power

A:From an ecological standpoint - very bad. Fossil fuels like oil and coal produce lots of greenhouse gases. Coal is one of the most polluting fuels used today. For countries that have much of it it may be considered good because it is a source of fuel, but in general it's a very dirty and polluting fuel. bad for the environment as the burning of it releases carbon dioxide from it (as it contains a lot of carbon), which is a major greenhouse gas and leads to more global warming. A:the disadvantage is that you would be causing global warming also they will eventually run out and it would force us to use other resources such as solar hydro water and electricity other then that it should last us another 200 years A:Fossil Fuels are said to be a cause of acid rain from the emissions they produce, which contains sulphur dioxide. We do have ways of removing these harmful emissions. It is just up to us to take the action. A:The basic problem with coal and other carbon based fuels in not really that they release carbon-- it is that the carbon they release is not then quickly and efficiently absorbed by some other process, eliminating it from the atmosphere. We are taking unimaginably huge quantities of carbon, stored away for eons, and pouring it into the air. It will remain there for eons more, until the earth goes through more of its own balancing cycles.

In contrast, take as an example the possible use of bacteria for the production of carbon-based fuel resulting from their consumption of grasses and other forms of biomass. If this process can be developed in such a way that carbon-based fuels are not a significant part of the input, then we know that the next generation of grasses or other plants will take from the atmosphere the carbon that the fuels are putting in. This is radically different from what is happening with current consumption of fossil-based fuels. This kind of technology is being seriously studied.
