Substitutes to Fossil Fuels
All human activity counts on energy; it is nearly impossible to live
without it. It is needed everywhere. Without it we will lose all the
modern technology. Now the number one source of energy is fusil fuels,
but after about 50 years they will be finished, so it is important to
start thinking about a substitute. That is what I am going to show.
This project is giving a solution to the problem of energy sources. I
am going to look at the electrical source (the most important). The
electricity stations will all use three systems. It will use the main
three sources of energy in nature:
· Waterfalls, Rivers
· Wind
· Sun light
[IMAGE]Waterfalls and Rivers: in every waterfall there will be an
electricity station, which will transfer the kinetic energy using
turbines to electric energy. In the summer the ice on the top of the
mountains will melt, so there will be lots of rapids. To get benefit
from these rapids they will be guided to a path where they are used.
Fast flowing rivers especially in Europe will also be used in a
similar way.

Wind: wend force will be a secondary source because it is not
reliable. In windy days wind turbines are used to produce power. This
power will be used in stage 2 of the project to store energy.
[IMAGE]Sunlight: Sunlight will be used in the hot deserts. There huge
space is found to put large solar cells to produce the energy needed
for the countries that don't have any water energy.
Stage 2:
Stage 2 is mainly storing energy. At night the power is not needed
that much, so electricity will be lost. Prevent this from happening
this power will be used to rise water up a manmade waterfall. Then
when energy is needed then the water, which was raised before, will go
down again through turbines to get energy. This stage is basically
about storing lost and/or unneeded electrical power.
Its most known process of generating electricity would be movement of air through wind turbines. Wind power has two parts, mechanical and electrical systems. Mechanical systems are low speed and are used for mechanical tasks such as pumping water or grinding grain. Electrical systems are high speed and are used to generate electricity to power homes or schools. Many people feel that wind farms full of turbines, are aesthetically unpleasing, but wind power is a clean energy source and does not generate greenhouse gas emissions. It is a very abundant resource throughout the United States. Wind power is simple, relatively cheap, and low maintenance (Sambu). Wind power is again, free and very abundant so no matter how much we use now, we will still obtain enough in the
Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.
In 1908, the U.S. Geological Survey (USGS) predicted that the total future supply of U.S. oil would not exceed 23 billion barrels. In 1914, the U.S. Bureau of Mines predicted that only 5.7 billion barrels of oil remained. In 1920, the USGS proclaimed the peak in U.S. oil production was almost reached. In 1939, the Department of Interior declared that there was only 13 years of oil production remaining. In 1977, President Jimmy Carter claimed, “We are now running out of oil.” Despite these predictions, the U.S. has produced over 200 billion barrels of oil since the early 1900’s. (The Futurist, 1997)
The U.S. may be in trouble when it comes to oil, but there are ways we can solve this problem. One way is to try to find alternative energy sources. We should research hydro-electric power, nuclear power, solar power, wind power or other possibilities. With an alternative energy source, we would not have to cut out oil completely, but we would n...
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Just as long as wind continues to blow and the sun shines, then wind power can produce energy to send to many different areas. There aren’t many locations that have continuous wind. And because of that, the widespread development of wind power isn’t as great as it could be. Although there are more advantages than disadvantages when it comes to this energy source, the disadvantages should be taken just as seriously. Wind power can harm animals, there was a study that stated birds were coming in contact with turbines and dying.
Fossil fuels are known as non-renewable resources; the amount in the Earth is limited. On the other hand, renewable sources of energy, like solar and wind, are those that will not be depleted despite their continued use. However, solar energy is difficult to harness and wind energy is not very efficient. The clear choice of renewable energy is water. The Earth has plenty of water to use for power. After all, it is because of its great quantity of water that Earth is nicknamed the “blue planet.” Hydropower is entirely renewable because it is driven by the natural Water Cycle. Lakes and rivers that are used for hydropower will not simply run out because they are constantly being refilled by rainwater. In addition to being renewable, hydropower is superior to other energy sources because it is completely clean of carbon emissions. Once fully functional, dams power themselves and give off no excess gases. Power plants burn coal and pour unthinkable amounts of greenhouse gases into air. Hydroelectric power is a clean, renewable source of
We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out of fossil fuels. Our known oil deposits will run out in approximately 35 years, and if we increase the use of natural gas and coal to make up for the energy loss, our natural gas will last for 45 years and coal deposits will deplete in 75 years.
One efficient way to acquire energy is Hydropower. Hydropower is power derived from the energy of falling water or fast running water. This energy converter is harmless to the environment. Other ways will affect the atmosphere and the environment in a negative way. The most common device for hydropower is a dam. It relies on the water cycle. This is one of the oldest sources of energy.
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
The three fossil fuels- coal, crude oil, and gas slowly formed over millions of years. These days, we use fossil fuels to power everything- homes, buildings, cars, computers, lights, etc. However, fossil fuels deposits will run out soon, which is a huge problem. Extracting, transporting, and burning fossil fuels are dangerous. There are also many negative biological and environmental impacts that result from the use of fossil fuels, such as ocean acidification, groundwater contamination, land subsidence, oil spills, and global warming. Therefore, we should be trying to reduce our dependence on fossil fuels and explore alternative energy sources such as wind energy, hydroelectricity, and solar energy instead. Our world depends on fossil fuels, but they can also hurt us. Fossil fuels are both a blessing and a curse.
Hydroelectric Power Plant is when electricity is generated when water in an uphill reservoir flows downhill. The gravitational potential energy of the water changes to kinetic energy of the flowing water which drives the turbines to generate electricity. The efficiency is more than 90%. The environmental impact is Floods large area and affects the ecology of the area, May cause drought downstream if not managed properly, does not cause ai...
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical energy.

In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
