What are some pros and cons of energy efficiency?
Pros include less use of energy and generally less greenhouse gases, while the cons are increased cost.
Greater energy efficiency usually results in an improved environment as less fuel is burned (assuming its fossil fuels). However, these efficiencies are often the result of newer technology, which is often costly - at least in the short-term. High energy efficiency technologies often are more economic in the longer term. For example, a cheap inclndenct light bulb might cost you a dollar or two, but this is a very inefficient bulb and you might need to buy a new one in a year or so. If you bought a high efficiency LED bulb, it might cost you $10 upfront, but it might last 10 years. So, there are trade-offs.
