Advantages And Disadvantages Of Using Renewable Energy

Energy is an important part of life producing the power of movement, heat, and production of electricity in many different ways. Therefore, choosing the correct source of energy is important for the environment and humans. Renewable energy that produces electricity never runs out, causing a lower environmental impact. Solar, Biomass, Wind, Geothermal, and Hydropower energy should be used globally to produce electricity. On the other hand, producing electricity from nonrenewable energy sources can be very harmful to humans and the environment. Humans can easily be dependent on it, which may not be the best option when it comes to finance, efficiency, sustainability and more. Approximately 52% of the US electricity comes from polluting sources like natural gas, oil, nuclear, and hydropower that have a lot of disadvantages effecting the environment in a negative way.

` The continuous use of fossil fuels is leading the Earth on a path to destruction. Generations of advancement and technological innovation being brought down to rubble. Natural disasters wreaking havoc on innocent people across the world. Temperatures soaring above 125℉ globally. These are the results of the excessive use of fossil fuels. A chief concern in the 21st century is global warming and climate change, and the continued use of fossil fuels for the technology and daily lives of humans is key to blame. Decades ago, these problems were much more daunting and seemingly unsolvable than they are today, with the use of alternative energy sources and new

Nowadays, global warming is causing terrible damages from climate change such as powerful typhoons, hurricanes, tsunami, super flood to human lives. It has become a big issue since the changes have happened more frequently. Therefore, many scientists are struggling with finding some alternative sources of energy to fossil fuel which release a great amount of carbon dioxide that have affected global warming. Governments also struggle with finding some possible solutions to deal with climate change. They are encouraging and investing on researching new energy sources. Bioenergy and solar energy have been highly used as alternative energies. This essay will explore the advantages and disadvantages of bioenergy and solar energy. How governments encourage spreading renewable energy in the specific countries will be described.

Although the United States has come a long way in the field of Renewable Energy, there are still major roadblocks in the way of a national shift to clean energy. Renewable energy made up only 12% of US energy production in 2016, while The three major fossil fuels—petroleum, natural gas, and coal—accounted for 78%, showing there is still a long way to go (eia.gov). This has been a particularly arduous year for environmentalist and renewable energy companies alike as there have been major political strides against clean energy. Bills, Executive Orders, and new laws have slowed the progress that Renewable Energy has been making in recent years.

By 2030 the world is expected to be more economically friendly and efficient when it comes to resources. Advanced technologies are being created to accommodate to the worlds high demand of energy. With all the emerging innovations, are world is becoming something far greater. Renewable resources are the key, they are the

Nowadays, environment and health scientists are concerned largely because of the damages caused by conventional energy. In most cases, these damages are happened because people are more likely to use fossil energy instead of renewable energy. In 1991, the worst disaster happened in the Arabian Gulf, and it was closed to my hometown. It’s estimated more than 250,000 seabirds died by oil spill (Laura Moss, 2010). However, solar and wind power is the best choice for many scientists to preserve the environment. In the past, renewable power had some difficulties because most of the energy has obtained from hydroelectric levees, whereas now produce more than quarter of the globe’s energy (reading 1). As well as this, more than 85 of the consumed around the world comes from fossil fuel energy. Unlike renewable energy, fossil energy notably pollutes our plant. Due to population and other reasons, renewable energy becomes more popular and getting attention from a lot of people (reading1). Ultimately, there are some differences and similarities between solar and wind power in terms of their amount of energy and advantages, and these sources has fundamental way to store their energy, which is through advanced battery.

Climate change is an inevitable and evident problem that has been debated on for quite a few decades. The role of energy usage towards increasing or decreasing the rate of change in climate and causing global warming is a very controversial topic in this world which exponential growth of population and economy. The amount of energy used and the type of energy used is also one of the key factors that contribute to this debate. Fossil fuels such as coal, natural gas and oils have been dominating the energy usage in the world and without doubt they create these unavoidable externalities such as pollution. The purpose of this paper is to

After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution, cheap fossil fuels then became the main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This essay will give an outline of three sources of renewable energy to be used in developing nations, which are solar energy, wind power and biomass. First, it will give a definition of fossil fuel and renewable energy, then it will move to analyse

Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.

The demand for electricity it is increasing in recent years, mainly because the world population is also increasing. The necessity for power generations is a constantly subject across the globe and is from that point that the concept of renewable energy emerge and become an important subject.

In today’s world of scarce resources energy efficiency and renewable energy become increasingly important. It is also well-known that the climate-change as a result of high CO2-emissions, among others, can only be stopped or at least slowed down by reducing these emissions. The general global trend therefore should move towards an increasing use of renewable energies while gradually stopping dependence on non-renewable energies, such as coal or oil. Despite trade-offs in terms of a possible rise in energy prices and impacts on security of energy supply, most developed countries have recognized the general need of a change. (Röpke, 2013)

In the world that we live, the prospects for renewable energy will increase in the European union as a whole, and in the UK in particular, in the coming decades. Renewable energy sources are already providing a significant proportion of the world’s primary energy, and it is likely to be providing a much greater proportion of the world’s energy by the second half of the 21th century. The European Union countries may do something to increase 20% of all energy from Renewable sources by 2020 to the society.This essay will outline the benefits and limitations of two common renewable energy sources, then, it will discuss how the topic suggestion is realistic in the UK context, and finally, what need to be done to increase renewable energy to 20%

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.

Energy is the most outstanding ingredient for socio-economic growth world-wide. It exists in various forms like mechanical, chemical, electrical, heat, light etc. There is minimum amount of energy required for life sustainability. Most especially from the food we eat but fuel energy is needed in cooking and in some climate, for heating houses. Research has shown that in 2008 for instance, the world wide consumption rate of energy was estimated at 500 exajoules per year (EJ)/y. The importance of an energy system is to secure energy service in the industrial, transport, house hold and service sectors of the economy. Energy, invariably is the fulcrum of growth of national economies. Fossil fuels are carriers of hydrocarbon substances. They include coal, crude oil, and natural gas. Its consumption depletes at any rate. Typically, the looming energy crisis is sequel to consuming these fossil fuels at a rate that is practically unsustainable. Besides, when consumed, fossil fuels upset the natural balance of carbon dioxide in the atmosphere, giving rise to various environmental tipping point. Effects of this carbon dioxide natural imbalance has its long term contribution to global warming and green house effect. Conversely, renewable energy systems are resources available on cyclic basis and include solar, hydro, wind, tidal, wave, geothermal and biodegradable biomass (fuelwood, animal and crop residues, energy crops etc). They do not deplete on consumption. The application of

Having relied on conventional energy sources for so many years which cannot renew themselves at a sufficient rate for sustainable economic extraction, as well as the growth of energy demand causing global energy crisis nowadays, it is becoming clearer than ever that all the countries have to look for other alternatives to try to tackle this issue. Therefore, renewable energy is considered to be a long term solution that might be able to replace the traditional forms of energy in the future. For instance, in the UK according to the Department of Energy and Climate Change, (2012), the primary consumption of electricity increased by 1.2% in 2012, at the same time the production of fuel dropped by 7.3%, additionally, the Office for National Statistics predicts a population growth of 1.3% by 2037. This illustrates that with the growth of demand for energy supplying as well as the predicted
