TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we

does that have to do with climate change? As China and its neighbors economies grow‚ the need for more energy increases. In order to meet their energy demands‚ industries have to use fossil fuels for energy. Fossil fuel burning accounts for 75% of the total global energy use (Ciserone‚ 2000‚ p. 1). When fossil fuels are burned‚ greenhouse gases are released into the atmosphere thickening the air‚ trapping heat and other pollutants increasing the chances for climate change thru human induced activities

Environmental Issues and Awareness Global warming‚ ozone depletion‚ acid rain‚ energy and water deficits are all problems that challenge humanity and its progress. However‚ the aggravation of these problems can be prevented through education‚ awareness and action. Industrial Art is a field of knowledge that encompasses innovations and advancements for technological progress and environmental welfare. Global Warming is a process in which Earth ’s average temperature increases due to the emission

The moon’s gravitational energy is responsible for the ideal effect‚ which give rise to tidal power. The earth itself is the key source of energy such as the following: Gravitational energy for hydroelectric power Chemical energy for nuclear power‚ electro- chemical reaction and hydrogen fuel cells.

dissent and division among the country’s citizens: nuclear power. It’s no secret that in the past decade or so the United States has been actively seeking to curb its dependence on nonrenewable fossil fuels such as coal‚ foreign oil‚ and also oil and gasoline that is produced right here in the country. Fossil fuels are known to be harmful to the environment and their steeply rising costs in recent years have caused a significant negative impact to the economy.

Depletion of Natural Resources - Oil DEPLETION OF ENERGY RESOURCES Modern industrial society is based on a triad of hydrocarbons‚ metals‚ and electricity. The three are intricately connected; each is accessible only if the other two are present. Electricity‚ for example‚ can be generated on a global scale only with hydrocarbons. The same dependence on hydrocarbons is true of metals; in fact the better types of ore are now becoming depleted‚ while those that remain can be processed only with modern

When people think of air pollution and ozone depletion they almost always and only think of exhaust from cars and factory smoke stacks but that is another reason this article stood out which is the fact it states in that “The electricity sector is responsible for more than a third of greenhouse gas emissions

from various roles in society have offered speakers’ worries‚ warnings‚ and solutions. Among them‚ Richard Heinberg‚ a leading educator on peak oil‚ is regarded as the world’s most effective communicators of the urgent need to transition away from fossil fuels. In his book‚ The Party’s Over‚ Richard Heinberg emphasizes the emergent condition that energy resources will be run out. He also addresses essential questions about practical solutions to the energy crisis. Heinberg mentions “a more strident voice

Economically‚ hydropower stations are several times more favourable compared to thermal power stations keeping in view the life cycle costs‚ recurring fuel costs‚ environmental cost and grid economy. Hydro power stations utilise water‚ as a zero cost input energy source against which there is a constant escalation in cost of fossil fuels used in thermal power station‚ thus making the operational cost of thermal power stations ever increasing. Electricity generation from the hydro is always

The cost per unit of energy is also increasing day by day due to the depletion of available resources. Therefore development of alternative resources of energy is important for the survival of humanity. Ocean wave energy provides ample scope on the renewable energy
