I think they are similar, but the cost of coal varies widely and transport can cost a lot. The costs of nuclear look good on paper but cost overruns are frequent and present predictions are not reliable as no plants have been built for a long time, in the US at least.
Materials that allow electricity to pass through them easily, such as metals. The best conductor is silver, but other metals such as copper and iron are also good conductors, while being a lot cheaper.
Yes...all metals are will conduct electricity.
The cost of electricity varies from country to country and between suppliers. Consumers can also have different tariffs so that it is cheaper to use electricity at times when others are not using it. There is, therefore, no simple answer.
Well, hydro electricity is cheaper because on on hand you don't have to burn fossil fuels in order to rotate the turbine and on the other hand you don't have to pay for it's drawbacks ( for example nuclear waste is very expensive to be thrown away). I should add that in some countries like those in middle east especially the Arab ones, as fossil fuel is very cheap and available, they mostly use it rather than other nature friendlier kinds of energy.
Solar panels receive energy from the Sun and use it to produce electricity. They are much cheaper to maintain than oil-powered electricity generators and oil storage tanks. Solar panels are also friendlier to the environment because they let off less pollution to the atmosphere compared to the smelly emissions which come from oil tanks.
coal
The only advantage of producing electricity from coal is that it will cost cheaper.
hydro electricity is better than normal electricity because it is cheaper.
Its Cheaper to burn and create energy.
Natural gas used to be much cheaper, but with rising oil prices its about on par with electric now. The price for gas will most likely continue to rise though. So, electricity is cheaper.
Glass and electricity, mostly.
One can get cheaper business electricity through rebate programs from various suppliers. One such company, SRP, will do a free lighting audit which will help you use energy-efficient products.
It may be due to finding of various other methods.
the water wheel changed the industrial revolution akot. this was a cheaper way to make electricity and cheaper.
Nuclear energy releases no greenhouse gasses and in comparison with solar energy, it's way cheaper. It also produces cheap electricity, France has the cheapest electricity in Europe and the get almost 80% of their electricity from nuclear power plants. It's also highly sustainable, contrary to what many think. Bernard Cohen proved that we can last billions of years on nuclear energy!
Yes, they are.
That would depend on the amount of each, and on local conditions.
