Energy efficiency is, at its roots, the concept of using and wasting less energy. Many of the most pressing threats to our everyday lives are the results of our (meaning humans) failure to achieve energy efficiency. Of these threats are global warming, diminishing resources, economic turmoil, illness-causing air pollution, reliance on fossil fuel, etc. Examples of energy efficient energy sources include solar energy, wind, and water. Harry Verhaar, head of global and public affairs at Philips Lighting and chairman of the European Alliance to Save Energy, gives a very refreshing and inspiring take on energy efficiency that we should all try to adopt. “Its logical,” he says, “because we simply waste too much. Some people call energy efficiency low-hanging fruit. I would even say energy efficiency is fruit lying on the ground. We only need to bend over and pick it up.” The successful implementation of energy efficiency would ultimately benefit the global community in practically every way possible. Climate change would ease up, our huge rates of pollution would decrease, and our reliance on unsustainable resources such oil, coal, and fossil fuels would be reduced. From an economic aspect, scads of jobs would become readily available in fields such as building upgrades, energy-efficient vehicle manufacturing, and the engineering of energy efficient everyday appliances such as lightbulbs, stoves, houses, etc. Not to mention, the massive weight of an impending economic collapse due to diminishing resources would be lifted from our shoulders. As can be seen in Figure 1 below, we are only decades away from reaching our absolute maximum rate of unsustainable energy usage until we are bound by the law of limitation to cut back.
Despite the simplicity of Mr. Verhaar’s fruit analogy, there are many difficult complications that arise from making strides towards energy efficiency. Cultural inertia is a term used to describe the concept that humans are so incredibly adapted to their reliance on coal, oil, and fossil fuel that the sudden transition to using only energy efficient resources would cost unfathomable amounts of money and would bring some of the most influential companies in the world crashing to the ground. Other complications are public skepticism and financial constraints. Quite simply, nobody is sure enough that the transition to energy efficient resources will be worth the massive funding that it requires. Overcoming these hindrances will be far from easy but, whether, gradually or suddenly, we must eventually sever our reliance on unsustainable resources if we want our planet to survive.
