Isn’t it interesting that the US Government excludes food & energy inflation when calculating consumer price index (CPI) — the average price of consumer goods and services purchased by households. Realistically the price for energy has been increasing on a yearly basis. Natural gas over the last 30 years in the residential sector was 7.54%. Electricity has been increasing 4-6% per year depending on where you live in the USA. Consumers who purchase a solar energy system, solar photovoltaic (electric) or solar thermal system (solar hot water) they are protecting themselves from inflation.
Adding energy inflation to a solar energy financial analysis is a very important factor because only then you can see the true payback period of a solar energy system. Locking in the rate you pay for energy is one of the best investments you can make. The booming world population coupled with rapidly developing countries has created a global power play for energy resources, moving forward the cost of energy is predicted to skyrocket, will you have energy security?
