Over the past decades, geologists and scientists alike have determined that the Earth is running out of non-renewable resources, particularly those resources that provide us with energy that fuels our world’s economies, jobs, and most importantly our daily lives. Without this energy, whole countries can collapse, and the human race would struggle to survive. Therefore, it is safe to assume that we as a nation are entirely dependent on energy, or the ability to do work (Gale Science in Context). Consequently, we are now actively searching for more cost efficient and useful forms of energy to replace those we currently use. By doing this we will be helping the earth by reducing carbon emissions and cutting down on air and water pollutants. This may ultimately prolong the life of our planet, and save money and resources while doing so.
While the quest to find the best sources of energy may not necessarily be an easy one, there are many forms of energy to consider when determining the type that would make the most sense to make use of based on our goals and parameters (such as finding a cost effective source that will be beneficial to the environment). As briefly mentioned above, energy is the ability to do work, and it can be observed in many forms throughout the universe. Each form of energy has unique characteristics, as well as a certain impact on our lives. Various forms of energy include chemical energy, electrical energy, light energy, nuclear energy, sound energy, and thermal energy. Though each of these forms of energy has unique properties, properties, and uses and therefore work together to help to power the world we live in. Chemical energy can be described as the energy released when substances undergo chemical reaction...

In summary, out of the six forms of energy, our nation is unfortunately heavily dependent on electrical and chemical energy. Currently, many of our sources that give us these two types of energy are unreliable and non-renewable, and are also very costly. However, if the Environmental Protection Agency were to focus on and allocate its two billion dollar budget to one form of energy such as chemical energy, as well as search for cleaner and more cost effective sources (such as wheat biofuel) of this type of energy, their efforts would help to reduce the effects of burning fossil fuels, reduce global warming, and indirectly provide a cheaper source of electricity for millions of Americans. This kind of initiative would protect the resources and environment of Earth while benefiting future generations of Americans to come.
The Environmental Protection Agency, or EPA is the result of a 1970 executive order by President Richard Nixon for the purpose of protecting the environment of the United States through regulation on business and citizens. Public opinion on the Environmental Protection Agency has been divided fairly evenly across the population of the United States as of recently, as compared to the widespread public concern of the 50’s and 60’s that led to the agency’s creation. Recently the agency has come under scrutiny for its contributions of millions of dollars in grants to researchers in order to hide the potential trade off of its actions in order to further the agency’s agenda. The EPA’s ever-expanding regulation could end up harming more than it actually
People need energy, it’s a fact. We need it for our cars, for our televisions and for our iPods. We need it all the time, every day. The simple fact is though, we are running out. Carbon based fuels are being used at an alarming rate every day. And every day our demand increases as our society becomes more and more reliant on technology.
Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
The purpose of this paper is to review the Department of Energy's (DOE) programs and recommend future directions for US policy to address President Obama's desire to save our planet from climate change and reduce reliance on oil (Roberts, Lassiter, & Nanda, 2010, p 4). The context of this review is following the 2008 election of President Obama and the enactment of the American Recovery and Reinvestment Act (Recovery Act) in February 2009. This paper will evaluate the effectiveness of the measures implemented by the Act and compare their effectiveness with an alternative strategy of implementing a carbon tax, then make a recommendation on which strategy would have achieved the President's aims in view of the political, economic and environmental situation that he faced.

What Nuclear power has the ability to do is get a lot of power in a little amount of space. “Roughly 1.6 billion people live without access to electricity, and 2.4 billion rely on traditional biomass because they have no access to modern fuel.” (General Dr. Mohamed ElBaradei) With nuclear power put into these countries that are without power we can have it to where electricity will be accessibility to everyone. By having power accessible to everyone we can accomplish so much more and unlock more possibilities in our world today.
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.
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. I believe the only way the United States and the world will see a large-scale transition to renewable energy sources is through education. Right now, it seems as though only a few pockets of people throughout the world are aware of the positive benefits of renewable energy sources. Not only is it better and cleaner for our environment, but the industry of renewable energy could also
Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by-product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Usually, once chemical energy is released from a substance, that substance is transformed into an entirely new substance.
Global warming is the earth slowly heating up and there are many factors to it. It is causing melting of the poles and water temperatures rising. One main factor causing this is carbon dioxide(CO2) emissions from the burning of fossil fuels to create energy. These gases being released into the atmosphere are also known as greenhouse gases. These gases trap heat within the atmosphere. While we need energy for many everyday uses there are a lot cleaner ways to make the energy. The public needs to be informed on the negative effects of creating energy this way and ways to make clean energy.
increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions… a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants (“Benefits of Renewable Energy
Hydrogen is one of the most abundant elements on the earth. It can be found in the oceans as well as the atmosphere. Over the last few years, talk about the future of hydrogen power has grown from a whisper to a roar. The use of hydrogen is not just the burning of the gas, but of its use in a fuel cell. Fuel cells might be the device that causes the extinction of the internal combustion engine. A fuel cell is a device that produces electricity from a fuel and an oxidizer, a substance that combines with the fuel. The fuel and oxidizer react chemically at two separate electrodes to produce the direct electric current; These cells use hydrogen as the fuel and oxygen as the oxidizer. Hydrogen power could be the silver bullet to the current and future energy situation.
The study of the relation between internal energy, heat, and work is the basic foundation in thermodynamics. How they interact can be applied to mechanics and experiments. For example, if you add heat to a piston, the gas contained inside will begin to expand and cause displacement, doing work. Gases are heavily studied in thermodynamics, because the internal energy is easier to account for. Gases only have kinetic energy because the potential energy is negligible since the far apart molecules cannot interact with each other. The four main types of thermodynamic processes- isovolumetric, isothermal, adiabatic, and isobaric-all involve the relation between work, heat, and internal energy on gases.
The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.
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.
