Alternative energy can effectively replace fossil fuels

I insist that the US should continue to use fossil fuels. My reason is that alternative energy sources can not meet energy needs, are costly, and most alternative energy sources are dangerous or unreliable. Fossil fuels are energy sources formed by collapsing organic matter in the Earth's crust. Common fossil fuels are petroleum, coal and natural gas. Alternative Energy: Energy generated in a way that does not deplete natural resources or damage the environment

First, alternative energy sources can not meet US energy demand. Although the two most common alternatives are wind and solar, from 2003 to 2007 these energy sources accounted for only 7% of the US energy demand, but other larger energy sources are It was maintained through fossil fuels. Another alternative energy source is ethanol, but because it takes 70% more to produce, it loses more energy than it uses. The tide can be ignored since it can not maintain all states again, but it may be important in rural areas, but not all states have a tide

Secondly, opponents who claim that the cost of using alternative energy sources is too high may say that it will promote the US economy and reduce dependence on foreign energy. This is a lie because alternative energy sources seem to have the same problem for everyone. There is no way to use them, there is no way to save them, not enough, and more costs will occur to get more information. The use of alternative energy sources will further involve the US in the debt crisis. Yes, wind, sunlight, biofuels, and nuclear energy are competing as a source of fossil fuel and primary energy, mainly because they are environmentally friendly, but their contribution to global total energy demand is limited It is. Due to problems of waste and disposal, it is much more limited

Third, most alternative energy sources are dangerous and unreliable. Although the only possibility to maintain US energy demand is nuclear power, there is no guarantee of safety. Waste disposal is a threat to our environment. It is always ideal to get fuel from water via hydrogen, but it is difficult to store and it is dangerous to handle. I forgot to mention important things, but there is nuclear fusion (geothermal) energy, but the 10 million fever of the sun is a big hope. Wind and solar energy have no way to store the energy they produce. Therefore, when the sun is not shining or when the wind is not blowing, there is no energy.

Can alternative energy be an effective alternative to fossil fuel? There is a hot discussion as to whether alternate energy sources such as biofuels, hydrogen, solar heat, geothermal, or nuclear power can satisfy energy demand more than limited fossil fuels such as oil and coal. Supporters of alternative energy think that fossil fuels are inefficient, unsustainable, environmentally destructive and are the main cause of global climate change. They say that renewable energy is a viable and immediate need for fossil fuel use that can promote economic development and reduce dependence on foreign energy sources. Opponents have argued that an alternative energy source must overcome many technical barriers before it can replace a small fraction of the electricity supplied by fossil fuels. They say that fossil fuels last for hundreds of years, become more efficient and still the most economical options and relying on inefficient alternative energy sources will weaken the economy.

An alternative energy source is an alternative energy source to fossil fuels. These alternatives are designed to address fossil concerns about fossil fuels, such as high emissions of carbon dioxide, an important element of global warming. Ocean energy, hydropower, wind power, geothermal energy and solar energy are all alternative energy sources. Over time, the nature of alternative energy sources has changed dramatically. It is also a controversy over energy use. The definition of several energy types as "substitutes" is considered to be highly controversial due to the diversity of energy selection and different goals of supporters.
