For one there are more than two renewable energy sources. These are wind, hydro, solar, wave or tide and geothermal (some people say tide and hydro are the same because they both use water). Also if you want to be technical they do not make electricity they change kinetic, heat and light energy into electricity. There are others and it is a lot more complicated but this is the jist of it and should answer your question.
Using NON RENEWABLE RESOURCES like Fossil Fuels, Petroleum Products & NUCLEAR Energy are methods that are harmful for Environment on EARTH and their usage should be reduced by generating Elelctricity through Renewable resources.
it is by solar, solar can bounce off of a solar panel and it can make electricity from the heat and power it is made in big power stations by things like fossil fuels and nuclear fusion but what the above is referring to is that there are many other ways in which electricity is made by renewable sources like tidal, wind, solar, waves etc. so yes both can be used to make electricity. :-)
To conserve non-renewable resources.
The difference between renewable and nonrenewable energy is: renewable doesn't make pollution, and also you don't have to spend fuel or other stuff just to generate electricity.
Non-renewable resources such as oil and coal will eventually run out, whereby it will stop providing us with energy. Renewable resources, on the other hand, will not run out. Examples like sunlight, wind, tree,water etc. can be used to provide us with energy as well after non-renewable resources have been exhausted. why are renewable resources important?!? well, because we need our resources.. energy, fuel ect.. but, we dont want to harm the planet to get them. So, we use renewable resources so we use resources that doesnt take away things from our environment that we cant put back in. That way we dont make the situation worse by removing important things from our planet, and also keep resources that we can continue to count on.
No, it gains its only electricity power from burning American flags which is renewable energy they have pledged to make under the Geneva convention to make two flags for every one burnt. Making it the most renewable energy source in the modern world.
we can make a green city by using renewable resources instead of the non renewable resources, and limiting the consumption of resouces and energy to the maximum. also by reusing the resources.
No, it only works when the wind is blowing. This is why renewable energy is best with a mix of resources. Solar energy, hydro power and wind are three that together can supply constant power.
The two most obvious are wind and sunlight. The wind will turn windmills which are attached to generators. Solar cells contain chemicals which produce electricity when sunlight hits them. This electricity can be stored in batteries and used when needed.
Depends. Solar energy can convert to electricity via solar cells. Wind energy can convert to electricity by turning a generator. Bio-fuels can burn to create steam to turn a turbine, or they can burn to generate thermoelectric power via dissimilar metals. Thermal heat from within the earth (earth-thermal) can make steam to make electric via turbines, or create electric via thermoelectric methods. Water flows through sluice gates and turns generators. In the future, we may invent micro organisms to go from sunlight to electric.
