Renewable energy is a term used to describe a source of energy that has the capability to refill itself. Renewable energy is sometimes called infinite energy. Renewable energy is also known as green or clean energy, because it does not produce toxins or pollutants that are harmful and dangerous to the environment.
Planet earth is going on a critical phase, due to the fossil fuels being consumed worldwide every day. Jimmy Carter once stated on a televised in April 18, 1977 that "Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy sources, like solar power."
Slowly and gradually those fossil energies would reach their ends, because they are quite limited. When that time comes, it could mean a major catastrophe for our planet Earth. Efforts are being made to replace existing hazardous fuels with new renewable energy.
Renewable energy has plenty of benefits to both our planet and us as people.
Firstly, this will help the Earth to regain back its lost power and there will be more greenery, more healthy living areas and finally pollution could be eliminated for good.
Secondly, renewable energy is infinite. Samuel Bodman once stated in a speech which he made in July 14, 2005 that “As the technology for solar cells gets better and better, this form of clean, renewable energy will find more applications that take up less space and produce more electricity, to meet the energy needs of our homes, schools and businesses” meaning that for generations and generations to come, renewable energy will be able to provide us a safe, clean and healthy environment for all people to live in.

... the sun’s radiant light and heat and converting these naturally occurring elements into electrical, thermal, and chemical outputs for practical use. This type of green engineering is called “Solar Energy Engineering” which involves state-of-the-art work on a wide variety of solar power systems, including photovoltaic panels, solar collectors, hybrid solar lighting equipment, and fuel cells. These efforts aim to reduce the consumption of energy derived from traditional fossil fuels.

Solar energy is energy taken from the light that reaches earth's surface from the sun. There are four different kinds of solar energy, which are active solar systems, passive solar systems, photovoltaic cells and concentrating power systems. An active solar systems is a system that captures solar energy by mechanical means. Common active solar systems are often in buildings or homes. Some examples are roof collectors and water heating. Low Intensity and high variability have limited the use of active solar energy in Canada. A pass...
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.
This solution will minimise greenhouse gasses like carbon dioxide which is released into the atmosphere, this will decrease our dependency on fossil
America depends on fossil fuels in many different ways, from travel to large industries. What will happens when the world runs out of fossil fuels? Renewable energies have the power to save our environment and change the world as we know it. Fossil fuels are not going to last forever. America has already started to implement renewable sources of energy, such as, wind mills, dams, solar power and nuclear power. Eventually we will need to utilize these resources in areas that are dependent on fossil fuels.
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).
... and monthly water filling. Solar energy is the cleanest and purest form of energy, allowing for cleaner air overall in our environment. There is great hope for a lot more solar panels to be installed worldwide. Solar is a viable alternative energy with solar panels becoming more affordable and more efficiently designed.
The current tendency of the world is to look at renewable energy resources as a source of energy.
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.
... Sunlight and heat will always be available to us because, it is a non-extinguishing resource and so, let us make use of it. With all these points made, there is no question that, solar energy is capable of becoming the world's future power supply. Works Cited Venables, M.

Energy can be put into two broad categories Renewable energy and none renewable energy. Renewable energy sources can be reused continually as they are abundantly found in nature. All of them are non-polluting but devices used to collect the energy may impact the environment adversely. They are free but producing storage equipment or converting them into another form of energy may be costly.
First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heats the panels, it produces electricity. Solar power produces energy during the day and can store energy for the night. Solar power does not pollute the environment. However, it has high maintenance cost, and it takes a lot of land space.
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.
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.
