The Eminent Future of Our Planet Earth


More and more people in the world are driving cars that run on oil. More and more people in the world are using electricity that is created by the burning of coal. These human activities have repercussions (like carbon emissions) that are drastically affecting the state of our planet. Due to these drastic issues, researchers and scientists have been trying to come up with other resources to be used as alternatives to fossil fuels.
So as to halt the problems of global warming, greenhouse effects, and other issues, people are calling for the transition away from fossil fuels. Some are calling for the usage of ethanol instead of oil. While others claim that windmills and solar panels are the future gateways for storing energy. With all of these alternative ideas, there are many others who are skeptical about the transition away from fossil fuels. In his article “21st Century Energy: Some Sobering Thoughts,” Vaclav Smil explains that given our rates of consumption it is going to be extremely difficult for this transition to happen. Even though Smil does have some interesting points, there is a bit of a flaw in his argument. Smil argues that given our current capabilities and the existing insatiable appetites of the world’s people, it is going to be hard to use new alternative energy sources. In other words, Smil believes in “technological sustainability,” and that the only way for people to progress is for them to change the methods by which they obtain resources. He says, “Other renewable energy flows (like those from windmills and solar panels) could not cover today’s worldwide total primary energy supply.” In other words, Smil believes that the lifestyles of humans should not be altered/changed. Instead, new innovations need to be created to allow for our ways of life to continue as they are.
As evidenced in his article, Vaclav Smil is extremely pessimistic about humanity’s ability to transition away from fossil fuels. He says that the scale of shift to a new energy source is going to be extremely enormous and difficult. Also, in his article it is stated, “today there is no readily available non-fossil energy source that is large enough to be exploited on the requisite scale.” The existing fossil fuels being used provide a lot more energy that any other alternative energy sources. So, there doesn’t seem to be any alternative energy source that has enough energy to keep up with our lifestyles and rates of consumption. Smil contends that storage issues would arise if human beings were to actually use windmills and solar panels. For example, “because wind and direct solar radiation are intermittent and far from predictable, they could never deliver such high load factors like those of thermal electricity generators.” All in all, Vaclav Smil is not confident about the reliability of using non-fossil fuels as energy sources.
With all of these pessimistic views that Smil presents in his paper, one wonders what our planet will be like if human beings did not “meet” the energy demands. Well, such an image reminds me of something stated in Professor Smith’s lecture. I think that the world would be a devastating and ugly one where countries are having wars over resources with many people dying because they don’t have the sufficient means to survival (i.e. food, water, etc). Such a world would also have many natural disasters like hurricanes and floods happening as a result of global warming. Such a horrid image could be contrasted to what our world would be like if human beings did make a difference to make the Earth a better place. I think such a world would be very communal where people would grow their own food and share it with those in their community. People would hardly ever use cars, and as a result the highway systems would become massive bike trails. This is a bit of a drastic idea, but it is something that could possibly happen if our processes became sustainable. Whatever the case, it is important to be educated about the state of our planet.
