Human Induced Climate Change (HICC) is the increase of greenhouse gases that is caused by human activities. This has led to warming of the climate, which causes problems such as increase in air and ocean temperatures and rising in sea levels. A possible solution to this issue is Alternative Energy Source. This is energy that is not based on the burring of fossil fuels. An area of an Alternative Energy source is Solar Energy. This essay will look at how Solar Energy is used, if Solar Energy is a good Solution to solve HICC and the positives and negatives of economic and environmental factors of Solar Energy.
Solar Energy is energy that has come from the sun. It can create either heat or electricity. Solar Energy is separated into two different categories Passive and Active. Passive energy is energy that has been turned into heat and Active energy, is energy that has been turned into electricity. Solar Energy is called intermittent source because it is not always available due to the sun being unpredictable. Even though it comes from the sun, which will never run out, if it is a rainy or cloudy day, the sun is not available to provide light. There are systems that have been built, that are designed with an energy storage feature, which therefore allows the user to continue to operate even when the sun is not shinning. As shown in image one solar power is a very simple process. When there is sunlight on the Photovoltaic Panels of a solar PV system, the sunlight is captured and converted into direct electricity. The number of PV systems that have been installed has increased of the last number of years due to the fact that it is a non-polluting clean energy source. The energy that a user will receive depends on the day. Insolatio...

...manufacturing. Solar energy is a completely renewable resource. This means that even when we cannot make use of the sun’s power because of nighttime or cloudy and stormy days, we can always rely on the sun. This can limit how much power will be saved for the future. One of the most important advantages with solar power is that is creates absolutely no pollution. Solar panels require very little maintenance is required to keep the solar power running.
The number of advantage that is associated with using solar power it ways out the disadvantage. Solar energy is a very useful energy source to contribute to solve the issue of human induced climate change. Solar energy is always going to be the most reliable resource because it is always going to be available. With an energy source like this one, that’s environmentally safe it satisfy the entire plants energy needs.
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...
On the basis of the evidence, it is accepted that climate change is occurring and the climate will change even further due to our fossil fuel based economy, the increasing number of people and their increasing wealth. The increase in greenhouse gases has already started having impacts on the climate, natural ecosystems and human societies. It is clear that the average surface temperatures have increased and it will continue to do as more carbon dioxide gets released into the atmosphere. The recent warming is unprecedented in both magnitude and speed. The projected warming for the 21st century will expect to create severe problems for natural ecosystems and human societies. Water resources are already suffering from increases stresses, and are likely to be reduced. This will inhibit the growth of crops and adversely affect other water uses such as water use for industries and the water supply for the human population. This will lead to more severe food shortages. The glaciers and ice sheets are already retreating, and will retreat more which will lead to changes in the total and annual cycle of river flow in some rivers, threatening water supplies further. Impact on the ecosystems will affect the distribution and productivity of plant and animal species and water supply. A loss of biodiversity is likely to be accelerated by climate change. There will be an increase in extreme weather events such as increases in flood magnitude and frequencies, increases in drought intensity, frequency and duration as evaporation rates will be greater. Higher average temperatures and possibly increased variability are likely to lead to increased frequency and severity of heat waves, causing additional deaths due to heat stress and vector-borne disea...
Ever since the advent of weather observation and prediction technology in the past 150 years, science has created a consensus that the earth is getting warmer, and that human influence is to blame. Some even blame this change, known as global warming, for bouts of extreme weather including cyclonic storms, droughts, wildfires, and heat waves. These scientists (and much of the public) believe that our influence is the problem, as our emissions of carbon dioxide and other greenhouse gasses, the product of the usage of our fuels, are polluting the atmosphere and trapping energy from the sun within. However, a minority group, scientists and public skeptics alike, believe this warming trend is merely a coincidence with the earth’s naturally cyclical climate, and that the activists are overstating something they know little about. Many even agree that if the prospect of our influence were to be true, the effects are not at all that bad, unlike what it is hyped to be. Thus, global warming has become a debatable theory. Much like legislation that prevents schools from teaching evolution as anything more than a theory, now there are also laws that mandate that global warming be considered debatable, and to argue both sides of it (Jonas).
There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores. The climate change is no mystery, it is known to be cause of various human actions trying to satisfy their needs while putting
Although solar seems to be excluded from most of the disadvantages listed above tied to using renewable energy sources, it still has two big main disadvantages. The first being that, it is impossible to shut off. The fact that there is no way to shut these solar panels off makes them prone to catch fire. This is harmful to the place they are located. It is especially bad when people put them on their roofs which can cause house fires. Another big issue with solar is that it takes a lot of room for the amount of energy that it produces. According to the U.S. Energy Information Association to produce 1 MW of solar energy, assuming that your panels are located in price sunny locations, it takes 7.4 acres of solar panels. When you compare it to the nuclear reactors that produce on average 770MW for approximately 500 acres of land. To produce the same amount of energy as one single nuclear reactor you would need approximately 5698 acres of land which is 11 times the amount of space that nuclear
The current level of carbon dioxide is approximately 398.03 parts per million (ppm). According to the data recorded at the Mauna Loa Observatory, in China, the atmospheric carbon dioxide level has been on the rise for the past ten years, with an average annual increase rate of 2.07 ppm. However, regardless of the current increase in the level of carbon dioxide, previous studies indicate that the current rate of global warming is lower in comparison to the historical data recorded for 450,000 years. This could be attributed to lower temperatures recorded during the prehistoric period. For instance, during the Jurassic period, close to 200,000 years ago, the average level of carbon dioxide was 1800 parts per million. This is approximately 4.7 percent times elevated, compared to the current atmospheric carbon dioxide levels. Furthermore, the level of carbon dioxide was higher during the Paleozoic era due to the existence of human habitats.
Nowadays, climate change is became a major global issue which are affecting our life such as global warming ,mean sea level changing and more extreme weather events etc .According to the research of Intergovernmental Panel on Climate Change 2007 ,it showed that the global mean temperature rose by 0.74 °C during the hundred year period from 1906 to 2005. Between 1956 and 2005,the rising rate was 0.13°C per decade in this 50 years , nearly twice the rate in the past 100 years. Eight (2010, 2005, 2003, 2007, 2006, 2009, 2012, 2004) of the last ten years (from 2003 to 2012) rank among the 10 warmest years on record. It seems that climate change is potentially affecting our life.In fact,human activities and natural effect are the causes of climate change.Generally,most of the scientists and government agree that human activities is the main causes of climate change rather than natural causes.Therefore,this essay is going to discuss why human activities change the climate more seriously than natural effect.Afterward,I will also present some possible solution to reduce the climate change.
Over time, scientists have been able to perform studies and gather the information as to what exactly causes global warming. Scientists have collectively agreed that humans are the main cause of global warming is human produced. Humans burn coal, oil, and other gases to create energy. In doing so, this creates excess carbons that warm the atmosphere that block the heat from escaping the Earth (Climate Change Causes: A Blanket around the Earth). This process is known as the greenhouse effect. Other gasses that contribute to the greenhouse effect include water vapor, carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (Climate Change Causes: A Blanket around the Earth). Another human activity that contributes to global warming is
In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on fossil fuels.
Interactions between human and the ecosystem have been operating for millenniums, and are impossible to eliminate, as each depends on the other in order to survive and flourish. However, as modern technology advances, as well as the increase in the world’s population, the need for natural resources begin to rise to an alarming rate which has started to gradually destroy the ecosystem. Recently, there has been an increase of sea levels in region whilst other rain-bounty areas have begun to experience their first droughts. This phenomenon is known as climate change. Climatologists have concluded that human activity has played a major role in contributing to the changes, therefore requiring extreme measures before this phenomenon evolves into a catastrophe. In this essay, we will discuss human activities that contributed to climate change, as well as addressing possible solutions to the phenomenon.
In theory some parts of the world might benefit, from a human point of view, due to global warming. However, at current rates of warming, local ecosystems will collapse and any objective measure of global benefits versus suffering would show much more suffering than benefits gained.
Preview: Today I will discuss the potential that solar power has to become this country’s main supply of energy and the latest research that can make solar power more efficient and cost effective. I will also present the environmental benefits that come with using solar power over other and more harmful forms of energy.
... 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.
Solar power utilizes the sun’s energy to produce electricity, unlike other sources of energy, which rely on continual mining for raw materials. Consequently, producing solar energy from the heat from the sun does not result in the annihilation of the ecosystem, compared to the extraction of fossil fuels (Bode, 2005). Therefore, with the use of solar energy, it will help keep the environment clean, thus helping to combat the issue of global warming, which is a threat to the world’s ecosystem worldwide. The use of solar energy will help save the worlds vegetation, and help prevent the effects of global warming in future.... ... middle of paper ...
Regarding solar power, Mistry claims that although the solar power does not generate pollution, it has a lot of costs. Building solar panels with photovoltaic equipment has high costs. For instance, a photovoltaic system for a home can cost around $35,000 (Kumar, 2012). However, if our goal for the future is to create a healthy environment, switching fossil fuels for solar power might be the best choice to achieve that goal. According to Kumar (2012), Solar power is a clean and renewable energy so, it decreases the dependency on fossil fuel and also reduces the air pollution.
