Power from Wind and Water

People are able to generate power from wind and water as well. These two are also renewable sources of energy that produce power by driving electricity-generating turbines. A variety of wind turbines ranging in size can produce considerable quantities of power, as much as several megawatts. Water, on the other hand, including steam, can drive turbines as well to generate power. Running water and wave energy are used to produce electricity in hydroelectric plants, while steam is used in thermoelectric power plants.

Fossil Fuels

Fossils fuels were formed through natural processes of decomposition of plants and animals buried under the earth’s crust over a long period. They include coal and petroleum products such as oil, paraffin and natural gas. Fossil fuels are nonrenewable in the sense that they take a very long time to replenish; we burn fossil fuels for energy at a much faster rate than natural processes can restore them.

Nuclear Energy

Nuclear energy is another arguably nonrenewable source of energy; it is sourced from chemical processes such as nuclear fission. Nuclear fission is the splitting of radioactive atoms such as uranium. This reaction produces heat that turns water into steam for driving electricity-generating turbines.

Thermal Power

Thermal power has been used as a natural form of energy for thousands of years in cooking and heating. Hot springs are just one example of this naturally-occurring thermal energy. With today’s rising power demands, geothermal power plants are attractive options for their cheap, environmentally-friendly energy production. However like all power sources, thermal isn’t perfect, and disadvantages temper the strengths.

Financial Costs

One of the primary advantages of thermal power is that the generation costs are extremely low. No fuel is needed to generate the power, and the minimal energy needed to pump water to the Earth’s surface can be taken from the total energy yield. Even considering transport, geothermal energy is estimated to save 80 percent of the costs associated with fossil fuels, such as oil and natural gas. The principal financial disadvantage of a geothermal system is its high initial installation costs. The longer a plant is operational, the more it pays for itself in the long run.

Environmental Impact

Thermal power is revered by environmental activists because it is completely renewable, does not use fuel to produce power and has virtually no emissions. It also helps reduce global warming and pollution and requires far less land than a coal mine or oil field. The only environmental disadvantage is the occasional release of harmful gases. Since thermal power operates by drilling into the Earth’s mantle, some poisonous gases can escape. These gases can be a danger to plant workers, who must wear protective equipment, but have little impact once dispersed into the atmosphere.

Job Creation and Hazards

Thermal power facilities create a number of jobs for local communities. Researchers, scientists and drilling workers are among the specialists needed for safe and effective operations. Disadvantages in this area involve limited workplace hazards, such as crystalline silica dust and exposure to extremely hot steam and water mains. Fortunately, these dangers are minimal, especially compared to other energy industries, like fossil fuels.

Location

A main disadvantage of thermal power plants is that they can only be constructed in areas where temperatures below the Earth’s surface allow for the production of steam over a long period of time. The type of rock in the region must also be easy to drill through. Extensive research is needed to find these key areas; and because of their rarity, plants are sometimes forced to operate in relatively remote regions. Both of these factors contribute to the high initial cost of starting up a geothermal facility.

Long-term Viability and Risks

In areas where there is long-term steam production, thermal plants can thrive and produce many megawatts of clean, renewable power. In these scenarios, plants quickly recoup initial costs. However, environmental factors can sometimes lead to a reduction in steam in a region, forcing companies to take the risk of potentially losing their investment. Lack of equipment or qualified personnel and the relative financial security of fossil fuel extraction by comparison serve as an added disadvantage, hampering the continued expansion of thermal power.

Environment Pollution

Environment pollution is one of the biggest threat to our current way of life. There are a number of sources of environment pollution, including air pollution, water pollution, ground water pollution, and land pollution. Of course noise pollution is another growing source of problematic pollution in our world as well.

Water pollution contaminates everything from the sea life to the sea grasses and flora that support the sea life. Our waters have become so polluted that fish harvesting and even swimming have become significantly dangerous. The Hudson River became so polluted that the Environmental Protection Agency (EPA) banned the eating of all sea life harvested from the river in the 70s and 80s at various points.

Water pollution reached levels that were so high that lead to a major movement to “Save the Bay.” The Chesapeake Bay lost most of its natural grasses, which hurt the blue crab and oyster populations. This cut into the watermen’s ability to produce a reasonable living while also cutting sea life populations down to dangerously low levels. It took nearly a decade to reproduce the sea grasses that were demolished through human activity. Boating, dumping, and overharvesting all played a role in reducing the bay’s ability to filter the pollutants and produce healthy grasses.

Land pollution and water pollution are interconnected. Land pollution is a hazardous form of environment pollution that affects everything from our drinking water to our crops to our natural ecosystems. Land pollution can be caused by runoff from the roadways, hazardous chemicals that most households use on a regular basis, and construction sites. Natural waste can also cause environment pollution that affects our ground water, making it highly dangerous to drink unfiltered. Microbes can enter the digestive tract and cause illness. These microbes can come from unprocessed waste that can seep into the groundwater and cause serious implications.

Environment pollution that comes from land pollution is a serious problem for natural ecosystems. Mining can cause the destruction of trees, streams, and the life that is supported by these elements. As the ecosystem is destroyed, the entire ecosystem from insects to large animals find that they do not have enough food or drinkable water and starve to death.

With more construction, industrial pollution, ground water threats, and air pollution causes, nearly everything we do has an environmental impact. Environment pollution is a chronic, widespread problem that seems no longer containable. Our cars, our electricity needs, and our housing needs all contribute to the destruction of our natural environment.

Saving the planet from destruction requires immediate action on everyone’s part.

Land Pollution

Air pollution is a common problem worldwide. Land pollution is the direct result of the activities that humans engage in.

There are a number of major sources of land pollution, not counting the general litter and trash that people choose not the throw away in a proper receptacle. Among these major sources are burial sources, insecticides and pesticides, construction wastes, human waste, herbicides, and mining waste.

Herbicides, pesticides, and insecticides are harmful to more than what they are designed to kill or deflect. When used in large quantities these products can pollute groundwater drinking supplies as well as rivers and streams. Moreover, they pollute the ground and land surrounding the area they are used. While these products were originally produced to save the farmers’ crops, residential use is at an all time high and the land pollution effects are severe.

Construction waste is responsible for several types of land pollution. The soil dumping, which is often removed from a construction site and dumped into a nearby river or bay, interferes with the natural filtration process that is necessary to keep the waterways cleaner. On top of that, the oils, paints, and toxic chemicals which are often dumped or run off the construction site cause major land pollution problems as well as water pollution problems.

The acid that drains from mines is terrible for the surrounding environment. In the process of mining, gases are released from the ground and the composite chemicals are left to run through the wild habitats, killing off wildlife and aquatic life, both vegetation and animal. Mining has been a core industry of some areas for decades, and the urge to offer cleaner mining techniques is now so vital that refusing to do so could endanger entire states’ health prospects.

The biggest problem that land pollution creates is the impact it has on the surrounding environments. Every form of land pollution kills off the habitats of land animals as well as aquatic life. The more we deplete these habitats the more the ecosystem is thrown out of balance.

Without a well balanced ecosystem, more animals die from overpopulation to under population. Aside from the moral issues associated with this, the survival of the ecosystem is vital to human survival. We depend on the ecosystem to provide more than merely the air we breathe, but to provide a wealth and richness that we thrive upon.

Land pollution is often visible, we can see deforestation, the effects of mining as the surrounding trees die off, and we can smell the effects on our shorelines and within our cities.
