A non-renewable
resource or finite resource, which cannot renew itself, is a one of the most
important energy resource in the world. Fossil fuels, for example coal, and
natural gas, are being consumed every day by human, so fossil-based resources
will become rare and too costly. In the future, we might never see cheap
gasoline again.
Fossil fuels can
produce significant amounts of energy. When I was young, Natural gas seem to be
useless, but Natural gas is now considered a very valuable resource in 2014. I
learned about Hydrocarbons in Chemistry lecture room last year. Fossil fuels are Hydrocarbons which have many formula, so I cannot remember all of them and I got bad grade in
Organic Chemistry. I also learned about renewable energy which might be a new
good resource for the world. Renewable energy has many advantages, for example
it produces little or no waste products and it will never run out. The first
thing I think about renewable energy is solar energy, this energy comes from
the sun which mean we don’t have to find it. Every country in the world can use
solar power, so we don’t have to make war to get it.
Another power that saves
on raw materials and provide large amounts of energy is nuclear power. It has
the lowest impact on the environment because it does not produce Carbon Dioxide
and any gases. The other advantage of nuclear energy is that it gives powerful
and efficient than other alternative energy sources, because of these
advantages many countries are putting huge investments in nuclear power.
However, costs of nuclear power plants is very expensive, and nuclear waste is
hard to destroy. Nuclear power plants might be targets for terrorist.
There are many ways to
save energy. For example, turn off any appliances you are not using, turn off
your computer not leaving the screen saver on because it will not save any
energy. You also can use Reduce, reuse, recycle method, which is an easy method
to conserve energy. Saving energy is good for you, your country, and our world.

Apart from nuclear power, I think we have wind power, solar energy, and water energy. I don't really like nuclear power because it's too dangerous if the workers are not skilled enough. The best way may be solar energy, it is clean and never runs out, especially in Thailand, our solar energy could power the whole country, judging from the light and temperature.
ReplyDeleteI not agree that solar power can power entire country because We spend 5 or 6 months in a rainy season which is not quite sunny.
DeleteI wonder: is it true as Bank writes in his concluding sentence that "saving energy is good for you, your country and our world"?
ReplyDeleteAs I read it I was reminded of the ideas with a long history in economics (Mandeville, Adam Smith, Hume, Keynes) that luxury, and extravagance, and even wastefulness, can be very good: if people want to use more resources to live more materially rich lives, such as drinking Blue Mountain coffee and enjoying the convenience of having their computer and other tools or toys always on, it stimulates improvement, creates more employment, leads to improved technology, and over all increases wealth for a nation. Surely these are good things? If silly aristocrats did not want to show off in the first horseless carriages, would we have cars and buses today?
On the other hand, if we all make do with less, might that not suppress an entire economy? This reminds me of economists today who worry when consumer spending falls because that reduces production, which reduces employment, which pushes families into poverty! And that's a bad thing. Might we not, in fact, have a duty to consume more to help the national economy?
And I think there is a connection here with some ideas in Wann's latest post: if people stopped eating the pretty awful stuff served at McDonalds, KFC and the like, how many employees would lose their jobs, and have no wage, high or low? Should governments perhaps be encouraging more fast food consumption, smoking and so on to help national economies?
My last comment started with thinking that I never turn off my computer and other things, and am very wasteful with air-conditioning. But I don't think using less is necessarily the best solution, even though it would selfishly save me some money.
