Fossil fuels are worst than hydroelectric power because when they are burnt to harness their energy, they release CO2, a greenhouse gas, this enhances the effects of global warming and as once fossil fuels have been mined and burnt, they are gone and will not reacumilate again for millions of years whereas hydroelectricity doesn't burn any carbon, releasing no CO2 and hydroelectricity's original source of power will never run out, making it much more efficient.
Yes. But we can prevent it, stop using fossil fuels and electricity too much and hopefully global warming can slow down.
We can stop Global Warming from getting worse by reducing, reusing, and recycling or by not harming the animals and their natural habitats. So we can stop Global Warming from getting worse which people do not choose to.
Of the major industrial nations, China eclipsed the US in total CO2 emissions in just the past few years. The US still emits more CO2 per person than China, however. India is working hard to catch up. Qatar, per capita, has long been one of the world's top CO2 polluters.
No, the opposite is true. The invention of the combustion engine meant that the fossil fuel, oil, was burnt, and is still being burnt in vehicles all around the world. So global warming would not be so far advanced if we had found other ways of propulsion.
It is too early to tell at this point, but many anticipate Hurricane Sandy will be worse.
In some cases, geothermal energy projects can have negative environmental impacts such as induced seismicity, release of greenhouse gases, and land subsidence. Additionally, geothermal power plants can be expensive to develop and have higher upfront costs compared to fossil fuel power plants.
If we can make enough changes, then we might be able to slow it down. We have to stop burning fossil fuels (coal, oil and natural gas). If we do nothing, it will get worse and worse.
Nothing much. Wind power is free, renewable, non-polluting, and doesn't cause global warming. Fossil fuels are all exactly the opposite, expensive, non-renewable, polluting, and causing global warming. Some birds get killed by the blades, but far more are killed on the electricity pylons, as well as by fossil-fuel burning vehicles and airplanes.
Yes. But we can prevent it, stop using fossil fuels and electricity too much and hopefully global warming can slow down.
They are not. It's the other way round. Fossil fuels (coal, oil and natural gas), when burnt, release carbon dioxide, a powerful greenhouse gas responsible for global warming. Wind turbines generate electricity without any pollution, using renewable energy, which is the way of the future.
The US is a net importer of fossil fuels which means that fossil fuels used in the United States come from foreign countries. If those fuels are needed to run the industries and cars that power the American economy, than the US can be held hostage by those foreign countries by their choice to deprive us of the necessary fossil fuels. This actually happened in 1973 with the Arab Oil Embargo, when Arab countries were incensed by US support for Israel and therefore cut oil production in order to hold the US (and other Western nations) hostage and force the US (and other Western nations) to cave to their demands to cease support for Israel. Thankfully, the US was able to remain uncowed, but other nations like Japan were in a much worse position and have pursued a Pro-Arab foreign policy from 1973 onwards.
Yes, hydrogen burns with oxygen to produce water vapor. However, producing hydrogen takes a lot of electricity, which is mostly generated from fossil fuels, so the net impact on the environment, for the same amount of energy, is worse than simply burning fossil fuels directly.
Both coal and petroleum are worse than natural gas. Without any scrubbers, the worst air polluter is coal. With scrubbers, it's a tough call. Oil in the form of gasoline, emits huge amounts of greenhouse gases. On a btu basis, I would suggest coal is the worst. See related link.
There is a tremendous amount of debate about whether nuclear power plants are good in any country. Nuclear power has several advantages: it emits no air pollution or greenhouse gases, and it does not depend upon fossil fuels (which are getting more expensive). The disadvantages are that if a nuclear power plant is not run correctly it can have a very destructive accident (such as the infamous Chernobyl incident) which is far worse than anything that can happen with other kinds of power plants; and it is difficult to dispose of the nuclear waste which they produce. Greater use of solar power and wind power would seem to be a better move.
Because if we harm the environment, that would make our life worse.
Burning fossil fuels, especially coal, is a dirty process. Incomplete combustion of coal and oil produces particulate matter. Heavier particulates produce an annoying dirty grit, and lighter particulates can be inhaled deeply and become a health hazard. In addition to the desired combustion of organic molecules, impurities such as sulfur also burn and produce potentially dangerous oxides. Since the air is made of 80% nitrogen, nitrogen is combusted along with the fuel at high temperatures, releasing nitrous oxides. Since fossil fuels are composed mainly of carbon by weight, all fossil fuels produce carbon dioxide when burned. In the atmosphere, the sulfur and nitrous oxides produce sulfuric acid and nitric acid, respectively, which can lead to acid rain. The carbon dioxide helps trap heat in the atmosphere - contributing to the potential warming of the earth. In this lecture-discussion we will examine major local, regional, and global environmental effects of burning fossil fuels. These are respectively particulates, smog and acid rain, and global warming. The importance of particulates has long been acknowledged, and major particlulate emissions control measures have been launched in many countries. Evidence for acid rain is readily available, and the effects from impact on forests and lakes to crumbling ancient Greek structures have confirmed its presence, but its overall environmental/economic importance remains a matter of controversy. It is now widely accepted that human activities have contributed to a noticeable average global warming trend in the twentieth century. However, there are differential impacts of this global trend on regional climate, agriculture, storm damage, and other effects in different parts of the world. This complicates both the assessment of global effects of atmospheric emissions and international negotiations over requisite changes in fossil fuel use.
Global warming refers to the long-term increase in Earth's average temperature due to human activities, such as burning fossil fuels and deforestation, which release greenhouse gases into the atmosphere. This warming occurs globally, affecting the entire planet and leading to changes in climate patterns, sea levels, and extreme weather events.
