Energy Alternatives: * Alternative energy is any energy source that is an alternative to fossil fuel. In a general sense in contemporary society‚ alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels‚ such as high carbon dioxide emissions‚ which is considered to be the major contributing factor of global warming. * This chapter discussed only a few of the possible alternatives to our current combustible energy generation system

impacts until it hits home in that all of sacred places‚ our wallets. Changes need to be made but can we afford it or can we afford not to make the move that will ensure our future for generations to come. Fist let us look at why we chose fossil fuels. The fossil fuels we largely depend on today are coal‚ oil and natural gas. They are called non-renewable energy sources. That description is actually another way of saying we use them faster than they form. Over 100‚000 times faster to be exact! So how
Premium Energy development Nuclear power World energy resources and consumption
Comprehension 1. Fossil fuels are abundant on our planet today and can be used to create many sources of energy which is why they are so prevalent. They are considered nonrenewable sources of energy because they take millions of years to form and because humans are rapidly depleting our fossil fuels faster then they can be created‚ which makes these fuels nonrenewable. 2. Fossil fuels were formed from the tissues of organisms that lived 100-500 million years ago. The energy these fuels contain came

The process of burning a fuel to change chemical energy into thermal energy is called a. heat. b. electricity. c. energy. d. combustion. ____ 2. The three major fossil fuels are coal‚ oil‚ and a. wood. b. natural gas. c. uranium. d. electricity. ____ 3. Fossil fuels are considered nonrenewable resources because they a. burn so quickly. b. are in such high demand. c. take hundreds

Energy Alternative Energy Alternative energy refers to energy sources that have no undesired consequences such for example fossil fuels‚ nuclear energy and falling water. Fossil fuels are coal‚ petroleum and natural gas. There are some characteristics of the fossil fuels that made the concept of alternative energy come into place. (Alternative Energy) One of the fossil fuels‚ Petroleum‚ forms a thin film around the grains of the rock where it formed. Pressure from the overlying rock and water move

much lower then the actual costs for the energy from fossil fuels(GAO‚ 2004). Solar energy is the next most energy efficient‚ with the next alternatives being geothermal and tidal. Consequently‚ non-renewable resources are those that can not be replenished or renewed. Most of these resources are fossil fuels like‚ coal‚ oil and gas (Berg&Hager‚2007). Unfortunately‚ a massive percentage of all the North America’s energy is produced by fossil fuels and over
Premium Renewable energy Fossil fuel Wind power
Renewable energy is energy from natural resources such as sunlight‚ wind‚ rain‚ tides‚ and geothermal heat‚ these resources are naturally replenished. Renewable energy does not harm the environment or deplete any of our natural resources like fossil fuel. Renewable energy is not subject to sharp price changes because it comes from natural resources. Biomass is currently the largest U.S. renewable energy source with more than two hundred existing bio power plants providing energy for one point five

very important? Or not at all? So is it necessary to encourage the use of renewable energy? The existing fossil fuels are running out. The usage of fuel increases year on year. Clearly fossil fuel reserves are finite - it’s only a matter of when they run out. According to CIA World Factbook. We consume globally every year the equivalent of over 11 billion tonnes of oil in fossil fuels. Crude oil reserves are vanishing at the rate of 4 billion tonnes a year . If we carry on at this rate our known
Premium Renewable energy Fossil fuel Natural gas
Plants are usually the organisms which do the photosynthesizing to produce food (energy) for themselves and the animals consume the plants and get food (energy) as well. Energy resources which obtain energy from plant and animal material such as fossil fuels; coal‚ gas‚ oil‚ biomass and food get their energy through this process. Due to the uneven heating of the earth’s surface by the sun‚ the cooler air mass is the cooler air mass is forced under the warmer air which rises; this is air flowing

to deal with real challenges for its energy supply‚ especially if this country turned to a sustainable way of producing energy. Thanks to an ideal climate for sugarcane‚ Brazil has a huge resource for supplying the world with the clean and renewable fuel. 88.8% of Brazil’s electricity in 2011 came from renewable energy sources. Wind power provided the largest contribution‚ with capacity up a massive 24.2% from 2011. This increase came as a result of the large amounts of money that were invested
