different sources of energy which can be used to generate electricity to sustain mankind and the economic activities. However‚ nuclear energy is considered as more reliable compared to other sources of energy. Moreover‚ energy sources can be classified as renewable and non-renewable sources of energy. Renewable energy sources are those which can be reused without depletion. Consequently‚ they cause less harm to the human health and less pollution to the environment. Wind energy is the energy from the

Renewable energy sources like wind turbines and tidal barrages are better for the environment than nuclear power and fossil fuels. They also have the potential to last forever. So why are they not being used all over the world? A reason for this is because switching to renewable energy as a primary source would cost a lot of money. Some countries don’t think it is worth it‚ and others simply can’t afford to. There are also many nations that earn a vast amount of money from oil and coal‚ that wouldn’t

Right now we don’t care about it‚ but in a few years we will be facing the consequences of global warming and energy absence. That is why Ecuador should start concerning itself about our future as a country and as responsible humans‚ by the use of renewable energy; the perfect solution to these

which mainly comes from the burning of fossil fuels as a fuel source or for electricity. Alternative energy‚ also known as renewable energy‚ is a solution to the problems caused by fossil fuel burning. Many countries around the world are beginning to switch to renewable energy. Following this example‚ switching to alternative energy in America is a realistic solution to the problems caused by obtaining energy from nonrenewable sources. Fossil Fuels are natural materials

We want mankind to survive for a very long time‚ but if we keep using non-renewable energies the way we do‚ do you think we will be able to survive for a long time? I strongly believe that renewable energy is only part of the best way to prevent climate change. In this essay I

Urgent need for renewable energy Introduction In today’s world the most important thing human’s need is electricity. Without electricity most of the modern equipment would not work. Similarly fuel is needed to power transportation devices. Natural recourses such as coal‚ oil and natural gas are the basis for producing energy for all kinds of devices. Due to the extensive use of these resources they now face extinction. These resources are classified as non-renewable resources. In this report

Conserving Energy to Save Money According to an article and graph published in The New York Times‚ “About 56 percent of all the energy that is produced in the United States is wasted” (Revkin). With all that energy being wasted‚ Americans cannot afford to waste much more. There are a number of things a homeowner can do around and to their household to conserve energy and save money at the same time. They can turn off unneeded electricity and try other sources‚ such as renewable energy to conserve

In present day people all around the world have used many energy sources. For instance‚ cars have to use much fossil fuel energy. Coal and natural gas also have been used too much to heat homes and businesses even during the winter (Adapted from Rosenthal‚ E. ‚ 2010‚ December 11). As this information‚ ‘finding alternative energy sources is one of the major projects of this century in all countries because the world is running out of the natural resources’ (Edited extracts from authentic student
