According to the diagram provided, only 10% of the total energy used in the United States is obtained from renewable energy sources. Even though the use of biomass waste, a type of renewable energy, is only 5%, I claim that the United States should increase its usage above all other types of renewable energy.
The main source of Biofuel, another type of renewable energy, is the Algae, and they can grow rapidly in aquatic habitats that are unsuitable for agriculture, so there are no problems of competition between the algae and food crops. But then, “Algae farms require vast water surface areas to efficiently convert sunlight into an oil used as a biofuel”[1] (1). Also, wood, which is another type of renewable energy, [2] “provides heat, power,
America is threatened by the destruction of their own environment. United States is known for their innovation towards alternative energy like solar power, wind power and nuclear power. However , these alternative energies are not completely beneficial towards the United States.
Why don’t we use more renewable energy sources? What role do they currently play? According to Energy Kids, in 2008 renewable resources only produced seven percent of the energy that we used. One reason we don’t use a lot of renewable energy
It is believed that the world's supply of oil will last until about 2040. If you think about it, that’s not too far in the distance future. Oil is running out fast and we need to think of an alternate energy source. When we burn oil, we release carbon dioxide into the air which causes the earth’s climate to warm; a temperature rise of 3.6 degrees Fahrenheit could have serious if not devastating consequences. In the United States alone 60 percent of each person’s carbon footprint comes from the goods they buy, while the other 40 percent comes from their energy use at home, driving, and flying. That totals out to be about 10 billion tons a year. There are other energy sources but let’s think about the environmental and energy benefits of algae biofuel. Algae was first explored as a fuel alternative in 1978. Gas prices had skyrocketed, and the government was looking to help ease the crisis. The Aquatic Species Program run by the National Renewable Energy Laboratory, researched high oil-output algae for biofuel. After testing 3,000 types of algae, the program concluded that the algae, if...
I personally do not like windy days. However, wind could be helping us more than we realize. We could be using the wind to produce energy. This is what wind turbines do and now I will be researching them to determine the physics involved with them and how they work, their history, along with some statistics from the United States. Then I will go in-depth for the wind turbines of Texas, Washington, and Kansas and compare them.
In chapter thirteen of our book, Environment by Raven and Berg, it shows us just how important renewable energy sources are. Currently the United States of America thrives on the use of fossil fuels and nuclear power. The main problems with these types of fuel are that they are both limited and can be extremely harmful to our environment. They cause global warming, air pollution, acid rain, and oil spills (Environment), and not only that, but in the grand scheme of things, these sources really aren’t even that cheap of a fuel source. There are many alternatives to these all but outdated fuel sources.
A non-renewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption. In addition, Nuclear Energy, Coal/Petroleum/Gas (Fossil Fuels), and Coal are all examples of this non-renewable resource. Nuclear energy, uses Uranium to create energy, and is a non-renewable resource because once the Uranium is used, it is gone. Coal, Petroleum, and Natural Gas are considered non-renewable because they cannot be replenished in a short period of time; these are called “Fossil Fuels”.
The United States currently relies heavily on coal, oil, and natural gas for its energy. While the price of natural gas per barrel continues to plummet, the United States is constantly seeking new sources of renewable energy. Renewable energy consists of any type of natural resource (solar power, ocean power, wind power, rain, snow, etc.). that naturally and automatically replenishes itself. Renewable energy is important because it is infinite and everlasting, meaning our children and our children’s children will be able to utilize these resources long after we are gone.
In addition to the fact that solar, wind, and hydro power are local resources, they are also emission free resources. Emissions and pollution are a key concern with traditional power sources. The coal-fired plants that dominate U.S. energy production also produce more emissions than any other energy source. “Em...
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Our country is currently suffering energy-wise, we have been powering with inefficient sources for years now and the harm that it is doing to the country has started to become apparent. Renewable energy is the only way to stop, or at the very least, set back the inevitable downfall of our ecosystem. I think that the next big breakthrough for renewable energy is implementing off-grid communities that use renewable sources as their main sources of power, so that we can potentially escape the energy rut that we got ourselves stuck in. America is wasting their finite resources, such as coal and nuclear, when we could actually be using renewable sources that will never run out. Most of our country’s citizens have never thought about where their energy comes from, or they do not even care.
Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
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,...
The concept of this essay is to stress that biofuels are a viable and sustainable energy source than fossil fuels, showing its advantages but not ignoring its disadvantages which also enlightens us about the cleaner and renewable natural resources. Biofuels is an alternative source of energy which can end the global dependence on fossil fuels.
With the depletion of fossil fuel resources comes speculations and debates about alternative energy sources. The world, including the Philippines, is practically dependent on a dwindling non-renewable source of energy. Today, experts are debating about and considering three options: Nuclear, Solar, or Wind Energy. Everyone has been accustomed to the bad image of nuclear energy as a result of the Chernobyl and Fukushima incidents above all others. The popular belief is that radiation from a nuclear meltdown is very harmful to humans and other living things—which is true—and that nuclear power plants are very dangerous and not ideal—which is not. According to Smith, et. al (n.d), all the nuclear disasters that ever occurred were caused by human error and natural disasters like tsunamis, not one because of system failure. Putting the false beliefs aside, with proper engineering and adequate maintenance by experts, a nuclear power plant is a very ideal and viable source of energy for the following reasons:
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
