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.
Fossil fuels are worse than hydroelectric power because burning fossil fuels emits greenhouse gases, contributing to climate change, while hydroelectric power generation produces minimal emissions. Additionally, fossil fuels are nonrenewable resources that can deplete over time, whereas hydroelectric power is a renewable energy source that relies on water cycle replenishment. Lastly, fossil fuel extraction can have detrimental environmental impacts like habitat destruction and water pollution, whereas hydroelectric power generation has less of an impact on ecosystems.
Yes. But we can prevent it, stop using fossil fuels and electricity too much and hopefully global warming can slow down.
Humans contribute to the greenhouse effect by burning fossil fuels, deforestation, and industrial activities that release greenhouse gases such as carbon dioxide and methane into the atmosphere. These gases trap heat, leading to global warming and climate change.
Many countries contribute to global warming through greenhouse gas emissions, but the largest contributors are typically industrialized nations with high levels of fossil fuel consumption, such as China, the United States, and the European Union. However, it's important to note that all countries play a role in addressing and mitigating climate change.
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.
Wind power is generally considered more environmentally friendly than fossil fuels because it produces no air or water pollution and emits no greenhouse gases. However, some criticisms of wind power include its intermittent nature (depending on weather conditions) and the potential impact on wildlife, particularly birds and bats. Additionally, the production and disposal of wind turbines can have environmental impacts, though these are generally smaller than those associated with fossil fuel extraction and use.
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.
Burning hydrogen does not produce carbon emissions, making it a cleaner alternative to traditional fossil fuels. However, the process of producing hydrogen can still have environmental impacts depending on the method used, such as steam reforming of natural gas. Overall, hydrogen is considered environmentally friendly as a fuel source when produced using renewable methods such as electrolysis powered by renewable energy sources.
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.
