What is renewable energy? Renewable Energy is energy that has come from natural resources such as sunlight, wind and water. Renewable energy resources never run out. There are many reasons why I think that South Africa would be capable of requiring just renewable energy in the future. Here’s why…

One of the biggest renewable energy sources today comes from the sun. South Africa has a reputation of being known for their sunny weather for generally all year round. South Africa receives one of the highest percentage of sun and receives an average of 220 watts per metre squared on the annual 24 hour global radiation. Therefore solar energy would be the perfect option to be introduced across South Africa. Energy from the sun is harnessed using various technologies. Probably the most successful way of harvesting the sun’s energy is by using solar thermal energy. Solar thermal energy uses the light and heat from the sun to heat a fluid. The fluid becomes a gas/steam which supplies power to the generator which creates electricity. The reason why solar thermal energy is more successful tha...

    Renewable resources are resources that have the ability to restock itself in some quantity (Field, 2008). Thus, the amount of the resource available to be processed, is determined by the restock rate (Field, 2008). Renewable energy is commonly categorized with renewable resources. Renewable energy such as wind is beginning to take hold in many parts of Canada such as Alberta and Ontario (Jones, 2013). However, in Ontario, wind power has been seen as more of a problem than a solution.

    One of the most debated topics in twenty-first century politics is energy. As the world has progressively improved in technology, so has our dependence on energy. Energy comes from many sources, such as non-renewable and renewable energy. Non-renewable energy pertains to fossil fuel (coal and oil), natural gas, and nuclear. Renewable energy resources are hydro, wind, and solar. Since the industrial revolution most of the energy used has been non-renewable energy. These non-renewable energy sources have caused ecological problems, although there is disagreement to the extent. Energy reliance has also caused economic debate. Everyone wants to use the cheapest energy source. However, the cheaper energy sources have been causing the most ecological

    Alternative energy sources are renewable, and is most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things are expensive. There are several pros and cons that come with the utilization of alternative energy sources.

    When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

    Another alternative energy source is solar energy. This is predicted to be the most promising source of energy for the future, but there are still a few things that need improving to make it work in the most efficient way. Solar energy is produced when photovoltaic cells in solar panels absorb sunlight and convert it to energy. The energy from the cells is converted to electricity in an inverter and can be used or stored for later use. Solar energy is both renewable and sustainable. It is also a clean and quiet way to produce energy. Solar energy is good for remote or rural areas where it may be difficult to get power lines. Although solar panels are expensive to install they are low maintenance after installation. However, there is a need for a large, open area for the solar panels. Solar panels can only absorb energy during the day and even though the energy can be stored for use at night, it can be expensive to store energy. Solar panels are also less effective in bad weather when there is less sunlight to be

    There are different kinds of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from natural resources. Although renewable energy can be expensive to build, it has less environmental damage in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources.

    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 Pros and Cons of Renewable Energy

    Global warming is an extremely important and troubling aspect of the world’s current situation. This is due to the fact that the majority of the world’s energy production is from non-renewable energy sources, which are energy sources that either can not be naturally replenished or require thousands of years to be restored. Based on our current energy usage growth rates, there are an estimated 100 years left before our natural resource reserves are exhausted. (Non Renewable Natural Resources: How Much Is Left, Environmental Thinker) China alone consumes nearly as much coal as the combined usage of coal from the rest of the world. (US Energy Information Administration, China Consumes Nearly as Much Coal as the Rest of the World Combined) There is visible evidence of this happening with the increasing pollution levels. Carbon Dioxide and Methane pollution levels in the world reached a record high in 2012 and are 260% higher than the pre-industrial levels. (UN: CO2 Pollution Levels at a Record High, John Heilprin) Converting our world into a more renewable energy dependent society is the most advantageous and likely method for preserving our dwindling fossil fuel supply while also protecting the world that we call home.
