Session 8: Energy and World Change: Past, Present and Future

Energy and World Change: Past, Present and Future


Human beings have always needed energy. From energy derived from burning wood for fires to the energy that powers the computers we type on, energy has been changing.
  
We are coming to a revolutionary point in our existence. Most of us are no longer ignorant, intentional or otherwise to the dangers that come from our current energy consumption habits. Countries like China are turning towards green energy alternatives and Germany is already blazing a trail in renewable energy for the world to follow. A future where our energy patterns are sustainable is within our grasp! All the world needs to do now work towards it.

However, why are we so slow in the widespread implementation of all of this? Let’s take a look at some of the barriers to renewable energy.

Extra Reading:
Obstacles to Renewable Energy and Energy Efficiency:

This article was written for the Yale School of Forestry and Environmental Studies and was written by Richard L. Kauffman, CEO of Good Energies. In this blog post, I’ll be talking about the parts I find most interesting.

“The problem isn’t energy.” In this section, attention is brought to the fact that most US universities actually have the technology to create efficient renewable energy systems. However, most of these technologies are seeing use in places such as Europe. This is because renewable technology is seeing more promotion in Europe than in the US

“We’ve got the innovation deployment cart and horse backwards” Here, Kauffman states that most of us are waiting for than one miraculous breakthrough where the innovation in renewable energy makes it cost about as much or hopefully less than conventional sources of energy. Such a breakthrough truly would be miraculous but like most miracles, this may not happen anytime soon. In Europe, markets and incentives had been established to bring in industrial players, namely Siemens and General Electric to enter their wind energy markets with “good-enough” technology. Eventually these companies were able to innovate and create larger windmills at lower costs. Bring the technology in first and let innovation take its natural costs seems to be the solution here.

The playing field is not level. Among the notable barriers to entry for renewable energy is that it is more expensive than conventional sources. This is reinforced by the fact that some countries subsidise fossil fuels. If the externalities of fossil fuel burning are internalized (such as using carbon taxes) perhaps a fairer playing field would be established?

The last point I’ll cover from his article is “We don’t have the infrastructure”. I would say that this point tangoes with the “we’ve got the innovation and deployment cart and horse backwards” quite well. Without an adequate infrastructure, a country cannot utilize all of its geographical advantages. Areas with high wind speeds can’t channel their energy to those who need it and the same can be said for solar energy. If this isn’t in place than we can’t really implement policies to incentivize using renewable energy.

Key Takeaway points (from the lesson as well):
From what we can gather from most of the barriers above, every country most understand what is the main priority here. What is important is that countries around the world begin implementing clean technology as soon as they can. Like most industry beginnings, we have to start small. A market must be formed and nurtured. Once players begin serving that market, innovation, including increased efficiency and lower costs, would come naturally! Once the success and the low risk of such an industry is established, many other positive developments would follow.

Comparative studies are vital. In class, Prof showed us an interesting slide which compared the returns of using 1 square (kilometre) of land for biomass, wind farming and solar energy. Based on that study, solar energy trumped the other two in terms of returns for every square (kilometre) of land. Studies like this help to shape people’s perspectives and perceptions towards technology and can even help lay people (like me) truly appreciate the technology for what it can give.

Based on some of my readings, while gaining a sustainable source of energy is absolutely necessary, attention should also be placed on the efficient use of energy in general. Many studies have been conducted to show that energy inefficiency exists in many forms. From the loss of energy from conversion of its raw state to electricity, transmission and heating/ cooling and lighting the buildings, all these contribute to wasted energy. We can’t really complain that some renewable energies can’t provide enough for our consumption, we don’t really take steps to consume energy efficiently.

Ratings for the class:

Another consistent class for this week. Informative and fast paced without a dull moment in sight. 9/10 from me.
