I read an article this weekend discussing reasons that there has been a rising interest in cloud computing from businesses and why it will continue to do so in 2012. Of note in the article is the mention of energy efficiency being one of the drivers for the push to this technology.
It takes a team to solve energy efficiency problems. And the team members must be focused on energy efficiency so they have the products, knowledge, experience and interest to offer energy efficient products and services. Most tradespeople working today were trained to install products in the most cost effective way without consideration for long-term operating costs. But energy efficiency is all about long-term operating costs. So, if you and your tradesperson are just focused on his bill, you'll miss the big picture. The cheapest approach today may be the most costly in the long run.
