Fossil fuels are finite. Take crude oil, for example.
Our world lives on crude oil: addicted to it, in fact. Crude oil is a resource taken from the earth: in its most basic form crude oil are mineral deposits taken from the sea or land. It has been exploited for 150 years and a grand total of 7 million barrels a day are produced. At that rate, crude oil is bound to run out: in fact it will. British Petroleum (BP) said that at the end of 2013, there were 1.7 trillion barrels of black gold left. The world consumes a huge number (87 million) per day.
Do the maths: according to BP, we have just 55 years worth of the sticky stuff left in our reserves after 150 years of abusing and exploiting it. Fossil fuels just aren’t reliable enough to power the needs of our world for the time we need.Fossil fuels can pollute our environment. Fossil fuels (crude oil, gas, coal) turn into greenhouse gases once used. Figure 2 describes the elements/compounds making up the US Greenhouse Gas Emissions in 2013.
83% was carbon dioxide. Many scientists believe the earth’s temperature will rise due to rising levels of carbon dioxide: having a catastrophic effect on the environment. The earth is currently in an extinction process due to a number of factors . WWF considers the rate our planet has lost species to be 1,000-10,000% higher than the natural extinction rate. Rising temperatures melt arctic ice (making it hard for the polar bears we all love to hunt, making it hard for them to breed, making it hard to save those cute little fuzzies from the jaws of extinction).
In summary: fossil fuels wreck the environment. What Is A Solution? Solar power is one of the five most well-known energy solutions (hydroelectricity; wind turbines; biofuel and geothermal heating).Figure ThreeHow Does Solar Power Provide Energy? Solar panels allows photons (particles of light) to knock electrons from atoms, generating electricity. Solar panels are made of photovoltaic (when sunlight is converted into electricity) cells linked together. Usually solar panels are made of two slices of silicone, a semi-conducting material, placed in a sandwich shape. The photovoltaic cells establish an energy field.
Like magnetic fields, you need to have a negative and positive charge. To make this work, usually manufacturers ‘dope’ one of the slices of silicone with other materials, giving it the positive or negative charge it needs. More specifically, they add a layer of phosphorus to the silicone, adding extra electrons, giving it a negative charge. Solar Power Workings How Does Solar Power Solve The Problems Mentioned Before? Solar power is very reliable. The sun has a few billion years left on it’s clock, pretty much forever in the lifespan of humans. The sun will always be here to provide for our energy needs. The sun has created life on earth: controlling almost everything humanity uses (seasons, our calendar, etc).
Why can’t it create energy? However, one could argue that the resources creating solar panels would run out. However, there are other forms of energy: not everyone is going to hop on this method. Polluting the environment isn’t exactly on solar power’s list of functions. Solar power doesn’t pollute the water because it doesn’t rely on water.
Coal, natural gas, oil and nuclear energy all require cooling – solar power doesn’t. Solar power reduces air pollution. How? 31 percent of greenhouse gas emissions in the United States comes from electricity production where methane and carbon dioxide emissions are major contributors to global warming. Solar panels don’t produce any greenhouse gases when generating electricity. So not only do solar energy not pollute the environment, it helps solve a problem, even partially.
Thirdly, hazardous waste is a major problem: 400 million tons of hazardous waste are produced every year just in the US, and not all waste is thrown away. In Canada, 30% of waste produces just don’t meet requirements. The effect can be disastrous. It can affect the soil, negatively affecting plants and animals. Additionally, workers can be exposed to dangerous chemicals.
Solar power doesn’t rely on fuel to run, which means no greenhouse gas emissions. Solar power is a very good solution.

Fossil fuels generates millions each year. The fossil fuel industry is huge. There are 1,469 oil and gas firms listed on stock exchanges around the world, worth a combined $4.
65 trillion. The second largest company in the world, ExxonMobil, is worth at 425 billion and ranks after Apple. ExxonMobil produces oil. Not a surprise. Not to mention, that there is a plethora of countries reliant on oil for their main industry, especially in the middle east. Saudi Arabia produces 11.
75 million barrels a day, Iran 4.13 million and 3.23 million for the UAE.
The five biggest oil companies have a combined profit total of 137 billion dollars a year, or 375 million a day. The oil industry is huge. However, everybody knows their industry is a dirty business and is linked to greenhouse gases. In order for those companies to keep in business, oil companies lobby governments to ignore concerns. In 2009, oil and gas companies spent a record of 154 million in lobbying. Combined, the two traditional energy sectors paid out nearly 10 times the $29 million that alternative energy companies allocated for lobbying efforts.
Environmental organizations spent at least $21.3 million last year on lobbying.Bibliography
