Energy is so intertwined with everyday life that sometimes it is easy to forget just how much we depend on and use it. But what is energy exactly? For a word we throw around daily, it is surprisingly hard to define. In this section, the word "energy" refers to power and focuses on power produced from oil, gases, nuclear plants, biofuels, and renewable resources.
The biggest concerns in energy debates are how to continue meeting growing global energy demands without compromising the environment and how to replace the dwindling sources of coal and oil. Oil is the most used energy source in the world and has the highest input-output ratio, but oil is a finite and nonrenewable. Although the current generation has a (mostly) secure influx of steady, cheap energy, the same cannot be guaranteed for the future. If action is not taken in the present day, it will be too late when the problem of limited resources presents itself.
The quest for renewable resources has been underway for many decades now, but it has received new attention and support only recently. Wind, solar, and biofuels have all been successful in providing a good source of energy, but are not efficient enough nor cheap enough to compete with oil and coal. Even natural gases, which are considered to be the "cleanest" of carbon-based energy, is heavy with methane gas and carbon dioxide emissions. Advancements in technology and innovation are essential if we want to see cleaner forms of renewable fuels that can keep up with energy demands.
