At first blush, the economics of energy efficiency seem straightforward.
A business installs lighting controls or some other improvement. The business then sees its energy costs drop. From the savings, the business repays the investment over weeks, months or years, and then turns a profit on the
In my inaugural post, I went over why solar makes sense from a financial perspective. It is a sound investment that will provide you at least a 10 percent return on your initial investment for the next 30 years. Now the question is, “Hey Chris, how do you make money on solar?”
The answer is that solar saves you money through a program called net metering.
To start off this explanation, it is good to review your utility bill. Your utility bill has in it many line items for supply and delivery broken out into many different costs per kilowatthour (kwh). Kilowatt-hours are measurements of power used by you over a period of time, usually the billing cycle.
In recent years a greater emphasis on MPG during car shopping has emerged. Between fluctuating gasoline prices, a broader selection of hybrid vehicles, and the promise of plug-ins and battery electric vehicles, and mandated increases in CAFE standards, fuel economy is becoming an important vehicle characteristic for many consumers.
Makers of ICEs are looking to accentuate the efficiency of many of their “traditional” models to meet federal requirements and better compete with hybrid vehicles. This includes the addition of a turbocharger, which enables manufacturers to use smaller engines while increasing fuel economy by up to 20 percent. Turbochargers reduce emissions as they burn exhaust gas as fuel, and also provide additional power for acceleration.
“We will have solar energy as soon as the utility companies solve one technical problem – how to run a sunbeam through a meter” — anonymous
There is a lot of buzz going on these days about the role solar will play in the current clean tech revolution occurring around the world. Many people find solar interesting but don’t know how it works, why it is gaining so much popularity and how they can get involved. Below are some of the resources I have used to make the world of solar easier to understand.
First question to answer: What is solar? For this you should read the wiki description of solar power.
Now that you understand some of the history of solar power, you may want to understand one of the most common ways that solar power is converted into electricity, for this you should read about photovoltaics or PV.
A crash program to improve the energy efficiency of American homes, offices, and factories could slash energy consumption by 23 percent by 2020 and produce $1.2 trillion in savings, according to a report by the McKinsey consulting firm. McKinsey said that taking steps such as better insulating buildings, replacing old appliances, and sealing ducts is the fastest and best way to cut the country’s energy consumption. The firm recommended an investment of $520 billion in energy efficiency programs over the next 10 years, an amount that dwarfs the $10 billion to $15 billion included in the Obama administration’s economic stimulus package.
Is the world warming, cooling or does it matter? Most of us will say it matters, a lot, at least in public anyway. And especially if you are hoping to pay rent or retire one day with a career based around the belief that Amsterdam, New York and Dubai will no longer exist unless we cut greenhouse gases and stop the icecaps from melting. But what has happened now that the earth cooled over the past year? Not to mention former NASA Chief Scientist Dr. Joanne Simpson’s claim last year that now that she is “no longer affiliated with any organization nor receive any funding” that she can publicly say that she “remains skeptical.” Recently the name was changed from ‘global warming’ to ‘climate change’ – what is really going on? Or does it matter?
