If you want to create an effective energy policy for your company, you need to understand how energy consumption and production are likely to change in the foreseeable future. At least two broad trends are important to keep in mind. First, while renewable energy sources, such as solar and wind power, receive a great deal of attention, they will remain minor contributors to our overall energy mix. Nearly all our energy is derived from fossil fuels, whether petroleum, natural gas, or coal, and that will remain true for at least the next few decades. Second, demand for energy will continue to grow, keeping prices high.
