Alternatives Of Alternative Energy : Alternative Sources Of Energy

Solar power is the most abundant most renewable resource that we have and it is free. The process starts when the sun shines on Solar PV panels that have been installed on your roof. Photovoltaic refers to the scientific process by which solar energy is converted into electricity. There are a number of silicon cells within each PV panel. These react with photons, or units of light, from the sun to produce direct current or electricity. DC electricity then travels to an inverter, which converts this energy to electricity known as alternating current or AC that can be used in your home or office. AC electricity then travels to the distribution network in your home powering your domestic or office appliances. When your solar panels produce more electricity than your home or office is using, the extra electricity gets fed back into the national grid. Yet, there are many processes the PV cell actually goes through to produce power of electricity. The top and bottom layer of the PV cells are protective glass layers with conducting coding’s. Electricity in the form of electrons flows in and out of these conducting coding’s while electrical production process happens in the middle layer of the PV cell. At the molecular level, a photon strikes a dye molecule absorbed on the surface of the TiO2 causing an excited state, which releases an electron into the TiO2 that exists through the conductive layer. The

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

Energy is everywhere. Energy makes your car move, powers your electronic devices, and makes a bulb give off light. Where does almost all of this energy come from? Currently, fossil fuels are used to provide for 82% of the United States’ energy demand (Bradley et al.). The world is powered heavily upon a highly limited source known as fossil fuels. The world’s main sources of these fuels are being heavily deprived of. What will happen once these deposits become fully deprived of oil? The world will fall into turmoil unless we switch to an alternative source of energy as soon as possible. Alternative sources of energy are typically more expensive, although the resources are more reliable and green. Along with reliability, with modern advancements in technology, those alternative energy sources have the potential to take over the need for fossil fuels and become far less expensive to harness and utilize. The utilization of these alternative energy sources would not only fix the issues regarding the Middle East and having to rely on their harnessing of oil, but also many modern economic problems that are caused by this need for oil from the Middle East.

Alternative energy is defined as “energy generated in ways that do not deplete natural resources or harm the environment, especially by avoiding the use of fossil fuels and nuclear power.” It is one of the most commonly debated topics of this century. We are now coming to a time where energy can be created without harming the environment. There are many examples of ways we can get energy without harming the environment. Ways such as solar energy, wind energy, biomass electricity, hydroelectric energy and ocean energy, and geothermal energy. There are many pros and cons to alternative energy. Although it can take years for it to be something that the world can rely on, as a whole, altogether we can do it.

If America makes the change to renewable fuels, it could take hundreds of years to undo the indirect damage that will be triggered. The amount of pollution that would be emitted by harvesting new fuels is as devastating as not switching at all (Grunwald). The processes for acquiring these alternatives create pollution that will destroy our environment. It is counterproductive to use renewable energy, if it does not enhance the current situation. Many people are supportive of the change, but are unaware of the long term effects on the economy and environment. The issue of alternative fuels is a controversial topic around the world with numerous countries wanting to use a cleaner fuel source than petroleum and

Alternative energy sources can be implemented for house and car factories and any other facility you can imagine. The common known alternative energy sources are Hydroelectric Energy, Solar Energy, and Wind Energy. The potential energy stored in hydroelectric energy that is driving into a dam of water to make water turbines and generators. The energy that the earth receives from the sun is solar energy. Human civilization has started realizing how much harm they have already caused to the environment. Alternative Energy Sources helped people maintain balance of the nature without causing harm to conventional energy sources. Solar energy is a renewable form of energy will not deplete until thousands of years. It’s solar power to a generation is very clean. Wind Energy is an effective alternative sources of energy in places where the velocity of the wind is high but is a very clean form of energy. But the wind is a renewable source of energy therefore it wouldn’t make a big problem. The new alternative energy source is apart from commonly knowing that there have been recent advancements discovering to add of to the list of old alternative sources. Challenges by using the alternative energy sources are promised as the use of alternative sources of energy is under research to how to tap energy from other resources. Although the small powers of generation systems be brought into other places but the power generation from the resources on large scales are very challengeable with

Since the industrial age, fossil fuels have been used as a source of energy and power. The fossil fuels are used and converted into coal, oils, and gasses. The products of fossil fuels are mostly Carbon, which is harmful to the environment, leading to global warming and climate change, and O-zone destruction. These conditions cause global temperature increase, ocean acidification, rising sea-levels, health problems due to pollution, and the destruction of ecosystems (climate.nasa.gov). Considering these issues, alternative energy sources are something that can be used to help combat harmful fossil fuels and lessen humanity’s Carbon footprint (the amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a person, group, etc.).

My talk today is about energy especially about energy demands. What is energy? In physics, energy is defined as the capacity to do work. This capacity is very important to our daily lives, business, and education and even for the national security. This is why it is so important for world to meet the growing demands of the energy. According to Global future studies & research stated that there are 1.3 billion people are living without electricity today, which is 20% of total population and that 2 billion of population, is expected to be added to world population between now and 2050. Moreover, countries like BRICS (Brazil, Russia, Indonesia, China, South Africa) under rapid growth

Are alternative energy sources the answer to ending human dependence on oil? Right now there is no one substitute for oil because we use it for a variety of things. We can use alternative sources in areas to preserve or conserve our usage of oil. We use to use wood for fires and light. Then in the industrial revolution we began to use coal. “Coal can provide much more energy over longer periods than wood or any other biomass product. Forests were also diminishing in many regions because they were being consumed for fuel.” (Eric McLamb). Edwin L. Drake drilled the world’s first oil well in 1859 and launched the petroleum industry. Bach then

Some of the major on-going controversies in this decade are Keystone XL pipeline , fracking and climate change. These issues are co-related to each other and they all have one thing in common i.e energy from fossil fuels . Proponents for the Keystone XL pipeline & fracking argue that it would reduce the energy dependence on foreign oil. Although they are good for the energy security of the US, it may be a step backwards in terms of controlling climate change and looking for alternatives.

“In United States around half of million deaths each year are attributed to air pollution. It is estimated that air pollution each day kills three people in the city of Hong Kong. Air pollution also contributes to soil and water pollution. More than 15,000 people in the world die each day because of water pollution” (pollutionfacts.com). With these statistics, it is no wonder people are coming up with alternative energy sources. From energy to gasoline, there are many different ways to reduce these statistics. Some alternatives to energy sources are solar and wind power, alternative vehicle fuels and hybrid cars.

Renewable energy has become a widely popular topic in society. With the rapid depletion of fossil fuels, scientist are looking to natural and renewable resources to create a means to produce sustainable energy. There are many alternative energy sources that have proven useful in the past couple of years. Some of the alternative energy sources are not only more useful than others but have proven to be easier to attain and also prove to create a more substantial amount of energy. Today, the most widely used form of renewable energy is hydroelectric energy. Making up 20 percent of global electricity generation, hydroelectric energy is crucial in the production of electrical power and sustaining the environment.

The world currently faces a major problem. This problem is the need for alternative energy sources which can be converted into electricity because the main energy source currently used is coal and the coal deposits will not last forever. The main alternative energy sources that many countries are currently researching are wind, solar, hydro and nuclear. But there is currently another source of energy that is heavily debated to see whether the pros outweigh the cons. This energy source is natural gas. The main reason for the heavy debate of natural gas is not because of the energy source, but rather the mining process of the energy source through the process of hydraulic fracturing. In this report the following topics will be discussed to get a better understanding of natural gas and the hydraulic fracturing process. An overview of natural gas will be discussed. A detail description of the hydraulic fracturing process will be provided. The advantages and disadvantages of hydraulic fracturing will also be compared. Finally the report will look at hydraulic fracturing in a South Africa context and weigh all the information before deciding if the hydraulic fracturing process is advantageous or disadvantageous for the country to use.

There are many forms of alternative energy sources that take the place of typical fossil fuels. One of the most common uses of these sources for eco houses is solar energy. Solar energy is when sunlight is converted into electricity for use, most commonly through solar panels. Solar panels are comprised of multiple photovoltaic cells, which absorb sunlight and transfer it into standard DC electricity. Photovoltaic cells are usually made of silicon, a semi-conductor (Roaf, 202). Solar panels are commonly installed on the roofs of houses where there is little blockage of the sun. Almost all eco houses employ solar energy as a main source because no waste is produced. Solar

Over the past years, scientist began thinking deeper into the possibilities for energy that is renewable. They mostly looked into the sun as there number one source, the wind and other renewable options. Indeed, the sun for many years has provided heat for the earth whereby the energy it produces warms the earth directly and also indirectly. By so doing the heat makes water to evaporate lakes and other water sources like rivers and streams that eventually falls back to the earth and then filters into the ground.
