Solar Energy The Sun is a star and without it there would be no life on earth. This is why the Sun is called the ultimate source of energy. The Sun’s energy is produced by a process called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered

Why do energy policies differ from country to country? Energy policies‚ the manner in which a governments decides to address issues of energy development including energy production‚ distribution and consumption‚ are different in every country around the globe. This is mainly due to economic development‚ population size‚ geographical location and many other factors for example in the UK‚ as gas imports will rise in the future‚ the government has imposed a policy of trying to encourage the development

we have had a certain amount of new "alternative energy resources" been introduced to us. These new energy sources range from using almost all natural resources as suppliers. Some are quite complex while others just needed a little brainpower. One quite complex energy source is one of geothermal energy. Harnessing geothermal energy is an art in itself. It is the process of capturing the Earth’s internal heat in the core. This and many other energy sources are being implemented today to build a better

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

Renewable Energy Today‚ many countries mainly developed nations are dependent on non-renewable energy sources such as fossil fuels (oil and coal) and nuclear power. People call these sources‚ non-renewable energy because they cannot be regenerated or replaced once it is used. These sources are sources that exist in a limited amount on earth. University of California College (2009) state that over 85% of the energy used in the world is from non-renewable supplies. Most of countries in this

Energy drinks have been increasing in popularity‚ especially among teens and children. Due to several articles in the media about negative health effects experienced by people who consumed too many energy drinks‚ some parents and school personnel have become concerned about their growing popularity specifically among teens and children. However‚ if you are aware of how much caffeine you are consuming‚ people of all ages can safely consume energy drinks in moderation. Caffeine is the primary ingredient

issues in today’s world is that of energy sources to power an increasing global demand. Traditionally‚ humans have converted energy from natural resources like coal and natural gas for use. However‚ these sources of energy are both nonrenewable and cause large amounts of pollution. As we progress through the 21st century‚ renewable energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because

Solar Energy Solar energy in one form or another is the source of nearly all energy on the earth. Humans‚ like all other animals and plants‚ rely on the sun for warmth and food. However‚ people also harness the sun’s energy in many other different ways. For example‚ fossil fuels‚ plant matter from a past geological age‚ is used for transportation and electricity generation and is essentially just stored solar energy from millions of years ago. Similarly‚ biomass converts the sun’s energy into a
