Global warming is very real and prominent within our society, and it is happening because of humans and our carbon dioxide emissions. We need to find a way to counteract it, and I propose using renewable energy sources, such as solar panels, and wind turbines. Burning fossil fuels is one of the main contributors to the amount of carbon dioxide emissions. If we can replace fossil fuels, such as oil, coal, and gas, with renewable energy sources, we can cut down our CO2 emissions.
   Many people believe that it will be too expensive to replace coal and other nonrenewable energy sources with greener, renewable energy sources. According to greenpeace.org, this is a complete myth. In fact, the coal plants cost 6 cents to make per kilowatt per hour, while a unit of electricity from the wind costs 4 cents, which may not seem like much now, but it certainly adds up.
   Using renewable energy is certainly a quick and relatively easy way to reduce your carbon footprint and  help reduce global warming.

I agree, renewable resources are the way to go. However there is also the question of jobs. According to Energy in Depth, it is estimated that 3.8 million permanent jobs would be lost with a net loss of 1.2 million jobs. I think that this is the main reason that the US has not put more energy into the search and research of renewable energy.

Yes, the loss of employment is also one of the main reasons we have not switched to renewable energy. But, according to Peak Oil, oil resources will only last 190 more years. Think of all the carbon dioxide that will be emitted!
Another thing to consider: What happens when that oil runs out? What jobs will there be then? Renewable energy will create niche jobs to counteract that employment concern.

This is very true. I believe that scientists, researchers, and the government need to spread more information on climate change and the debilitating effects that it will have on our planet and society. According to ucsusa.org the aggregate national economic impact associated with these health impacts of fossil fuels is between $361.7 and $886.5 billion, or between 2.5 percent and 6 percent of gross domestic product (GDP). Which means that the economy would benefit from switching to renewable energy would increase despite the loss of jobs. This information needs to be spread through the United States if any headway is to be made because at this point in time people care more about the economy than the environment and the long-term effects of global warming.

This information does need to be spread, I agree, if we are going to convince anybody to switch to renewable energy sources. People might argue against the cost of implementing solar panels, for example. According to solarpowerauthority.com, installing a 5 kilowatt system in an average American house would cost about $25,000, which may seem like a lot, but it would pay for itself in the long run.  I believe that we also need to educate people on the detrimental effects of nonrenewable energy resources in order to help them learn to care more about the environment than the economy, as you said.

Yes, I agree that we need to replace fossil fuels. Most of the energy that we use comes from fossil fuels. In fact it is the reason for more than 80% of greenhouse gas emissions, and these gases are trapping heat which is what’s causing climate change. Several of the primary energy sources that we use daily are coal, oil, and natural gas. We use them for transportation, generation of electricity, agriculture, and many other things. Sources such as coal, oil, natural gas, and uranium are nonrenewable, and when they are burned “nitrous oxides causes photo chemical pollution, sulfur dioxide creates acid rain, and greenhouse gases are emitted.” That is why it is important to use renewable energy sources such as sunlight, wind, moving water, and geothermal energy.
    To reduce the amount of greenhouse gases, we need to make changes to our everyday lives. Families, businesses, and schools need to start replacing their old electricity sources with solar panels. Solar panels are clean for the environment since it is considered a renewable energy source. Also, coal is considered th e dirtiest energy source because it releases the most pollutants than any other source. Coal plants should be shut down and replaced with things such as wind turbines which use wind, also a renewable source. All in all, humans should be switching over to cleaner energy sources, that do not cause as much harm to our planet, helping us avoid making any climate change matters worse.

Replacing fossil fuels to biofuel may sound like a good idea to many people, however this comes with many great disadvantages than advantages. Biofuels which are created from biomass come from plants and sometimes food reduce carbon emissions greatly, and reduces a country’s dependency on fossil fuels. However, fossil fuels create jobs and may determine a country’s economy.

    Fossil fuels are a major cause of global warming and scientists are looking for a way to replace fossil fuels, and they did so by creating biofuel. Biofuel reduces carbon emissions however it doesn’t completely remove a car’s/airplane’s/boat’s carbon emission. Engine’s burn biomass which in turn creates carbon emissions, however greatly reduced because biofuel is made from biomass which is derived from renewable sources. Realistically, the world will never give up fossil fuels because if we do, it could create massive economic damages to countries that are distributors of fossil fuels. To put this in perspective, removing fossil fuels completely from the United States we would lose 25% of the power  o utput of the country. Not only that but Middle Eastern Countries, Russia, and other countries who export fossil fuels as a source of income, would collapse. Not only would they collapse but poverty would be widespread across these countries.

    Realistically, we cannot replace fossil fuels at this time. Although biofuels help reduce climate change the economy of the world would be greatly damaged if fossil fuels were taken out of the economy. Until new discoveries on renewable energy which are efficient and able to produce jobs in countries who depend on fossil fuel exports.

I agree that replacing fossil fuel is inevitable in the future, but it will take time. According to your source, renewable energy is cheaper. It seems like there's no reason why people would not switch from fossil fuel to renewable energy. But actually renewable energy is hard to be generated on a large scale and it is not a continuous source to supply electricity use. Plus, big oil companies have large influence on policy making and of course they don't want to see fossil fuel being replaced. And I think that's why renewable energy  is not able to be produced to completely replace fossil fuel. p.s.: I think our next energy source after fossil fuel will be nuclear energy generated by thorium.

Renewable energy will probably not be the only source used as an alternative to fossil fuels, I agree. It hopefully will be one of the major sources, however.
You mentioned that the next energy source used might be nuclear energy. Why might that happen? Especially in comparison to solar, geothermal, or hydroelectric power. What makes it more likely to be used than the other possible sources?

I agree that replacing fossil fuels will really help with the issue of global warming. Global warming is a very harmful and prominent issue in our environment and needs to be addressed. Clean energy is a big way to reduce our effect on the environment, especially because much of our modern day society needs energy. There are many possibilities for clean energy including wind power, hydropower, solar panels, and many more. I also think more human generated energy could be possible, as I've seen stationary bikes power blenders. It would be cool if we could find a way to make treadmills in gyms generate energy and even sidewalks.

I agree with all of you, replacing fossil fuels is in motion as we speak people all over the world are trying to replace fossil fuels for things like solar and eletric. The Car company Tesla has already made eletric cars.  the only problem with the two sources of energy is that they are both expensive. There are other sources of energy like hydroeletric, using dams, Geothermal,using the heat of the earth to power things, and wind, using wind turbines to ceate energy. they all have there flaws, but they are way better than burning fossil fuels. Climate change is becoming a large problem in the world using sources of energy, other than fossil fuels could greatly reduce the productio of CO2.

I agree that replacing fossil fuels would create a big impact on global warming.  Global warming is affecting our planet and it is becoming worse everyday. I agree with the idea of switching to electric cars because it will lower the rate  of global warming. There are many other things we could do to help our planet like using clean energy. We could use wind power, hydro-power or solar panels.
