‘’Fossil fuels are coal, natural gas and petroleum.’’ (http://en.wikipedia.org/wiki/Fossil_fuel) They are all organic residues. People use this for their energy, fuel and heating requirements. But fossil fuels polluting environment so much and people started to think about using alternative energy for their environment’s healthy. ‘’These alternative energy resources are windy power, solar energy and geothermal energy.‘’ (http://en.wikipedia.org/wiki/Alternative_energy) They are renewable resources and they pollute environment so much less than fossil fuels because of that many people want to use alternative energy for their environment’s health but many people want to use fossil fuels because of alternative energy is not much common and useful these days because it needs new investments and it’s really difficult to make it common in the world. In my opinion alternative energy cannot effectively replace with fossil fuels because it’s really expensive, risky and the earth is not ready for this now.
First of all, I should say that the equipment and the system for obtaining alternative energy are really expensive and nobody will spend millions for alternative energy without big companies. And I don’t think all big companies will spend these millions for alternative energy while they can make more profit from fossil fuels easily with these millions.
About risks, everybody know that is sun doesn’t shine solar energy can not work and also unless wind blow there will be not any wind power. Although, all people always need energy. If there is not energy for only one day there will be chaos and so many diseases.
The biggest issue is the world and people are not ready for this. Because there are billions of cars, ships, machines, buildings that working with fossil fuels what will we do with them also there is not many machines and buildings that are using alternative energy. And it will take a long time for people to get used to using new vehicles.
In conclusion, I don’t think alternative energy can effectively replace with fossil fuels because of high costs, taking big risks and the unprepared world for using alternative energy.

In a balanced energy regime, fossil fuels should be used only in specific areas with a limited allowance each year. In the future, fossil fuels can be used in less developed area with limited exposure to high-end technology, and it can be stored in fixed quantities as a kind of back up energy sources. I have several reasons behind my proposal. As mentioned in the book, fossil fuels have several major disadvantages. As a result, it should be gradually phased out. The author mentioned that mining itself can cause damages to human beings, generate greenhouse gases and acid rains, and cause mountaintop destructions. However, comparing to clean energies, fossil fuels have their unique advantages even in a balanced energy regime. For example, just…

The other aspect of the argument getting rid of fossil fuels causes a fear of hurting the economy. There is also the fear of losing money and jobs in the process of transferring over to alternatives. Increased energy demands coupled with a dwindling supply of fossil fuels can only result in disaster. It is important that alternative energy sources are found and utilized. New energy sources will not only make us a greener society but will free us from dependence of foreign sources and give us a technological edge in the globalized economy.…

By increasing the use of fossil fuels we are not only making this world running out of fossil fuels but also it has a negative impact on environment. Every drop of fossil fuel we use emits carbon dioxide in the environment. Increasing the amount of carbon dioxide in the environment is the cause of global warming, which is one of the major problem we are facing today. This global warming results in the climate change and due to climate changes so many species are endangered today. Instead of making ourselves more and more depended on these fossil fuels, we need to focus more on alternative energy resources. Instead of getting a huge big car we should prefer to buy a small hybrid car which gives good mileage. By doing this we will not only save fossil fuel and will save our environment as well. We live in highly industrialized country in the world. This country has a higher wastage rate than the other countries in the world. It has a little or no emphasis on pollution prevention, recycling, reuse, reduction of unnecessary waste and other form of conservation. Resource consumption and energy use is highest in the US than in any other country. US has 5% of the world population and its consumption is 30% of the world's natural resources. We need to focus on this human system in…

“Unfortunately, the process involved in using the fuels released fumes into the air that are harming the planet.” Since fossil fuels are not a renewable source it will eventually run out. “In 1987 the United Nations said that we should aim for sustainable energy.” Meaning countries should start developing sources of energy that will never run out or harm the planet. “Fossil fuel power plants burn oil, coal, or natural gas.“That heat produced is used to turn water into steam.” “The steam powers machines called turbines, and the turbines then power generations that produce electricity.” However burning fossil fuels also releases harmful substances into the air, such as oxides says Vic. “These oxides mix with water vapor and fall to earth as acid rain,” which is harmful to the…

Fossil fuels comprise 80 percent of current global primary energy demand, and the energy system is the source of approximately two thirds of global carbon dioxide emissions as of 2015 (Foster and Elzinga). For decades, people have argued about whether fossil fuels are helpful to the planet and sustainability. Although, there is no right or wrong answer because renewable and non-renewable resources have disadvantages and advantages. There are very many different variables to be considered in this argumentation. Fossil fuels make up most of Earth’s energy.…

In 1977, the President of the United States of America, Jimmy Carter, advocated for the use of alternative energy to the American people “because we are now running out of gas and oil, we must prepare quickly to strict conservation [of fossil fuels] and to the use of coal and permanent renewable energy sources, like solar power.” More than thirty years later his announcement still rings true and is relevant. In fact, the current situation of non-renewable fuels is worse than in 1977. This is because American and global society is becoming more mobile and active, which is causing fossil fuels to be diminished at a higher rate than ever. Scientific discovery like the innovation of steam power and river power in the nineteenth century was a catalyst for meeting energy needs. Almost two hundred years later, the time to update energy solutions has arrived. Even though people disagree, alternative energy is the correct solution to the problem of diminishing fossil fuels. Therefore it is imperative that alternative energy be used more often than non-renewable resources due to their renewability, benefits to the environment and humankind, and its ability to stimulate the economy with an independent energy market.…

Many people are debating how to best meet energy needs in the United States. Some argue that the country must decrease its dependence on oil and invest in alternative sources of energy. The United States use tons of oil daily witch tends to be very expensive. Many people believe that to best meet energy needs would be to find alternative sources, such as wind, and solar power. The simple fact is, renewable and alternative energy should be a major investment for everyone. Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and comfort. Individuals and organizations choose to conserve energy to reduce energy costs and promote economic security. However, Industrial, and commercial users can increase energy use efficiency. Repeated use of alternative sources would help the United States to gradually clean up pollution and also save millions of dollars in the future.…

Energy is the foundation of industrialized world; without energy, life as we know it would cease to exist. The yearly energy and fuel consumption rates have risen dramatically within the last years. This phenomenon is a direct result of globalization pressures, the international information network we call the Internet, and a population that seems to be hitting the dangerous upswing of the Malthusian curve. Although there is not yet a current shortage of conventional fuels, such as reserves of coal, oil and other fossil fuels are limited and non-renewable. In addition, the common practice of burning oil, coal, and other assorted hydrocarbons has resulted in hazardous environmental conditions such as global warming, acid rain and dangerously high air pollution levels. This and other environmental disasters have brought about a demand for alternative fuel and energy sources that are convenient, environmentally friendly, and economically viable. The U.S. Department of Energy defines alternative fuel as fuel that is essentially non-petroleum and yields energy security and environmental benefits. Following are some of the fuels the Department of Energy currently recognizes as alternative fuels methanol, hydrogen, liquid and compressed natural gas, and electric fuel. Alternative sources of energy are classified as energy provided from sources other than fossil fuels. This includes but is not limited to nuclear power, solar power, hydropower and biomass. Currently, many of these alternate sources are in use, but unfortunately they are underused or underdeveloped because of perceived shortcomings or drawbacks. While some of these fuel and energy sources may indeed lack the efficiency or cost effectiveness of the conventional fuel and energy, having a clean living planet far outweighs the cost of clean energy.…

Fossil fuels are being used up at a faster rate than they can regenerate. The British Petroleum report provides alarming figures. At the current rate of consumption, the coal reserves on Earth will be spent within 110 years. Global reserves of oil and natural gas are even lower, and will be spent within the next fifty years respectively. Despite these statistics suggest that fossil fuels are a reliable long-term energy source, these numbers are misleading. Due to global population and energy needs are steadily increasing, it is only natural that the consumption rates of fossil fuels will rise accordingly. This means that the projected time frames of the availability of fossil fuels will shrink exponentially.…

At present, fossil fuels are readily accessible. These fuels are easy to use, and a simple combustion procedure turns them into energy for running a vehicle, generating electricity and/or heat. Fossil fuels are currently a cheap source of energy and so are the methods of producing energy from them. With our present distribution networks, we can get fossil fuels of all kinds around the world. That makes it easy to employ them, no matter where you are. Thus, there is a huge dependence of fossil fuels. That means, as energy is running out, everyone will suffer the consequences. Not only will it raise the demand and price, but will also affect the political stand point of each nation- especially, the third world countries. As the demand of energy increases and the supply becomes more limited, nations will be competing for energy. Therefore, the focus will be less on innovation and more on gaining control over the remaining fossil fuels. Furthermore, as the cost increases, the process of innovation will slow down and seeking new form of energy will be expensive. Inevitably, fuel will ran out, our country will eventually have to choose between paying to continue the status quo and investing in a new form of energy for the future. Hence, making a decision now instead of waiting 25 years will only give a head start in finding alternative ways that will replenish the dwindling supply of energy today.…
