In recent years there has been great concern over the growing demand for energy, and the lack of non-renewable energy resources to meet the demand in the future. In addition, the question of “sustainability”—the ability to balance social, economic, and environmental needs in energy production to meet both current and long-term requirements—has come to the fore. It is clear that America must expand energy production quickly, and that we must develop renewable, sustainable energy sources to meet long-term demand and protect our future. There are many proposed solutions, such as wind and solar power. But the technology for these resources is not yet fully developed, making them, at best, low-output alternatives. Because renewable sources are

America should pursue alternative energy sources because “With only 5 percent of the worlds population, the United States consumes almost one-quarter (22.5%) of global energy”. (((Josef Bram, 15))) With such a small percentage of the world’s population and still one of the largest consumers of energy the U.S should be looking for new and better ways to generate energy. Currently The U.S’s energy is supplied using traditional sources. According to Canadian scientist and policy analyst Vaclav Smil “Todays energy 29% from coal, 33% from oil and gas, and 33% from soft-energy (alternative sources)” (((Smil, 47))) Most of the energy we use on a daily basis is not produced using clean methods. Some alternative energy sources that are already in place within the United Stats are wind, solar, and hydraulic.

Oil, gas, and fossil fuels have been recent controversial issues. There are cleaner forms of energy that could be used, but it is unclear what sources should be used and how to

that run off these alternate energy resources. We have done so much damage it will take a

These alternatives can be helpful in reducing carbon emissions while ensuring the energy independence . These sources are wind ,solar ,geothermal, hydro, nuclear and renewable bio fuels. Some of these sources are renewable , meaning they can be replenished, while others like nuclear, are non-renewable, yet are clean sources of energy. For better sustainability , society continues to explore the challenges of these energy options to help implement the necessary changes for an environmentally friendly and energy independent future.

to get clean energy for use of cars planes and other things that we use everyday.

One of these concerns is that the cost transitioning to clean energy would be too expensive. It is true that shifting to green energy would have notable start-up costs; however, generating energy from these

If renewables are not an option for increased power production, we will have to use one of the five base-load generators already in use: coal, oil, nuclear, natural gas and hydroelectric.

How to change the process so future generations can also be supplied with a reliable renewable energy source.

How astounding that by creating turbines, we are able to harness that much electricity. Creating jobs for thousands of workers and their families. Now what about solar? The Sun has been around since the beginning of humanity and how foolish of us not to use more of it’s natural rays. Consider harnessing the sun’s power to make electricity.

By using this, we would already have a renewable resource that covers 70% of Earth. I know that we have several dams built in my state. We can use the dams to run water through a turbine, which uses a generator to convert it into energy. Water is cheap to use since we have a such high demand of it, however, we shouldn’t overuse water. We have the water cycle, but that doesn’t mean if we overuse water that it’ll always be here. Also, most of today's water is highly polluted. That would cause an issue. It would always be available no matter the weather. Water is always

While these options are great, they just aren’t feasible due to the amount of energy that they can produce. As of 2014, the United States gets 39% of its energy from coal, 27% from natural gas, and 19% from nuclear, while only 7% from renewables. This shows that renewable energy accounts for only 13% of the United States’ energy consumption. If you consider wind, which is the most promising renewable source, it has the most potential, but not on the order of natural gas. Texas has the largest wind capacity in the United States, producing around 3,400 megawatts (MW) of energy. When compared to a typical Pennsylvania natural gas well, which can produce 28,000 MW, this is

more traditional sources such as coal or natural gas. In the article The Cost of

* It is the only source of electricity generation in hilly and remote, inaccessible areas where generation from other sources or transmission of power over long distances would not be feasible. Cost of building the plant and return on investment is fast compared to large hydro and hence would attract many private investors to invest.
