Advantages and Disadvantages of Renewable Fuels Solar Energy: Advantages: -Energy is free although there is a building cost. -Causes no pollution‚ however‚ energy may go into machines that produce pollution. -Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. -Estimated that the worlds oil reserves will last for 30-40 years whereas solar energy is infinite. Disadvantages: -Solar energy can only be harnessed when it is daytime

How Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of

Reports overview: China’s demand for fossil fuel has grown at a fast pace in the past decade. In the next five years‚ both production and demand will continue to grow. This new study examines China’s economic trends‚ investment environment‚ industry development‚ supply and demand‚ industry capacity‚ industry structure‚ marketing channels and major industry participants. Historical data (2003‚ 2008 and 2013) and long-term forecasts through 2018 and 2023 are presented. Major producers in China are

Man’s Dependence on Fossil Fuels Before the occurrence of the Industrial Revolution‚ fossil fuels were considered as temporary source of energy. They were only used to compensate for the lack of firewood and charcoal supplies that were the primary energy supplier back in the day. Although the first combustible fuel used widely which remained useful for a long period of time was wood. Advancement by both technological and social demanded a source that could provide a higher energy output. These sources

sources of energy. A sizable percentage of people hold the opinion that traditional fuel such as petroleum and nature gas should be maintained while others encourage people to use replaceable energy. As I see it‚ the new type of energy should be appreciated. People who support this issue have their own reasons. In the first place‚ it is obvious that fossil fuels are nonrenewable energy in out earth. The total fossil fuels are limited and if we consume them excessively and rapidly‚ the resource would

The "fuel cell cars" currently being advertised are being touted as "having no emissions except water." In a limited sense that is‚ in fact‚ true. However‚ if the entire fuel cycle for the car is considered it most certainly is not. The fuel used by the fuel cell is hydrogen‚ very pure hydrogen. Combined with oxygen from the ambient air‚ the fuel cell produces electricity that powers an electric motor and other devices in the vehicle--just like the battery-driven electric vehicles already on the

advantages of fuel cells over outdated batteries‚ there are still various controversies around the notion of using fuel. Society does not like to change (maybe try using alter or modify instead of change) their conventions. People get attached to certain things or methods of executing tasks and they refuse to give them up. This phenomenon tends to slow down the progress in technology especially the ones that are radically different from its ancestral technology. When considering fuel cells‚ one of

energy” refers to any form of energy that is not derived from fossil fuels. Alternative energy sources like wind farms‚ solar cells‚ hydroelectric dams‚ biomass fuels‚ and nuclear power have been considered to be attainable sources that will be able to sustain the global population’s high demands. Traditional energy sources like oil‚ gas and coal are what the modern world knows and is most comfortable with‚ as its established fountain of fuel. Weighing the benefits and drawbacks of one power source

Introduction to Physical Science: Energy and Fuels Energy is defined as the capacity or power to do work‚ such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms‚ such as electrical‚ mechanical‚ chemical‚ thermal‚ or nuclear‚ and can be transformed from one form to another. It is measured by the amount of work done‚ usually in joules or watts. All known forms of energy can be converted from one form to another. The Law of Conservation

will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us because of its abundance and power. We have simply
