Energy can be transformed but cannot be got rid of. There are lots of forms of energy but chemical energy is the most common form of energy. Energy is a chemical bond that combines atoms or molecules with each other. When the new bond is formed between to atoms the energy helps the formation. The energy that helps is normally heat energy but can also be light or electrical. When the bond is broken atoms get realised as does the energy in the bond.

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

Fossil fuels and other power generates are slowly changing the world. Alternative power sources are slowly becoming more popular in everyday life while the technology progresses. Using these power sources that don’t pollute the atmosphere could be the change in the world that completely changes the way the world uses energy. Engineers and technicians have been producing these alternative ways for years and years. A few, but not limited to consist of: Solar panels, Wind turbines, Wave tech and much more.

Wind energy is another renewable source of energy that could be a potential alternative energy source. “Wind power is the conversion of wind energy into a useful form of energy such as using: wind turbines to make electrical power, windmills for mechanical

Alternative energies are the future of power. They will be the power that will sustain human life until the end. This is why the United States government should invests more towards the research and use of alternative energies. Alternative energies are any energy that will replace fossil fuels. Some common alternative energies are solar, wind, hydroelectric, geothermal, hydrogen, and biofuels. The U.S. should use those alternative energies over fossil fuels, Petroleum (oil), coal, and natural gas. We currently have ways to store and use these types of energies but the ways we have are not the most effective. That is why the U.S. should fund the research of better ways to harvest and use these alternative energies.

There are two types of energy: kinetic energy and potential energy. Kinetic energy is energy possessed due to motion, and potential motion is energy which

First, wind power is one alternative energy source that America should pursue. Wind power is one of most noticeable of the main alternatives. The power of wind is captured using tall wind turbines or windmills. These turbines

Fossil Fuels are a great alternative but the technology is still relatively expensive and can be very dangerous to the natural environment. The ability to power more homes from the direct sunlight coming from

Natural gas is a fossil fuel trapped in between rocks and water bodies underground. Natural gas is formed underground from the deposit of organic matter over millions of years. Natural gas from the release of energy trapped in plants and animals. Plants and animals store energy from the sun in the form of carbon in the molecules of the plant or an animal. Once the plants and animals die they release energy from the accumulation of matter and heat. The varying amount of heat and pressure from the different types of biomass results in the formation of different fossils fuels and gas. Fossil fuels and gas move in between the rocks where they are trapped before extraction (Curtis

As a evergrowing country, we need reliable energy resources. We need sources that wouldn’t require a large plant, cause environmental effects, be cheap enough to afford, would be something that is easily replenished, and something that would be safe to use. For example, burning coal (a nonrenewable source) is not good for the environment. We are suffering consequences such as more holes in the Ozone layer from using more than needed fossil fuels. Pollution is also a highly equal problem we are facing.

There are six different types of energy: Kinetic, thermal, electromagnetic, chemical potential, spring potential and gravitational potential. Kinetic energy is the energy of movement. Thermal energy is kinetic, only on a molecular level. As molecules speed up, they become warmer. Electromagnetic energy is energy in waves, for example light or microwaves. Chemical potential energy is energy stored in chemical bonds, which break when it is released. Spring potential energy is energy stored in any type of spring. Lastly, gravitational potential energy is energy gathered in an object as it moves further away from the force of gravity. None of these forms of energy are ever created or destroyed, they only change forms. One example of gathering this energy is photosynthesis. Plants gather energy from the sun using photosynthesis. During cellular respiration energy is released in a form usable for actions the cell requires. Energy relates to evolution because the ways of transformation of energy have changed. For example the chloroplasts are specialized cells to collect energy from the sun, they evolved from the simple prokaryotic

Many people have been contemplating about which energy source would be the best to use, but a proper decision hasn't been made. Every energy source has their own benefits which contribute to a healthier environment, but with every benefit, there is a drawback. Not every single energy source is available everywhere. Solar panels would be inefficient in a constantly cloudy area, and a wind mill would be incompetent in stagnant air, as a hydroelectric dam would be incapable of anything in a desert. One peg couldn't sustain every peg hole at one time. Transporting the electrical energy would cost more money, which could become a disadvantage over time as the generators that transform the energy already are costly. Even though a great deal of time and effort have been put into thinking which energy source is better overall, the answer is still unknown since everything comes with it's own problems, so I have chosen the ones that I believe are more efficient with nature and costs.

All energy is divided into two different types of energy, kinetic and potential. Kinetic energy is energy that is in motion, to make the object or living organism move at a faster constant speed we need to put work into it, that force is called kinetic energy, an example of kinetic energy is Potential energy is energy that is stored but is

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.
