How to reduce your A/C costs by 30%

Happy Earth Week everyone!

I learned something new in the past couple of weeks.  We recently closed on a house (yay!) and one of the first things I mused with our realtor about was, “should we install A/C?”  The Bay Area in general has great weather, but the last few summers have had a few days here and there where temperatures were above 90 degrees, making it unbearably hot indoors as well.  Today happens to be one of those days - yesterday, temperatures were almost 90 in our apartment, and today, it definitely went past the 90 F mark.  It’s hard to resist the temptation to install A/C on days like this.

Anyway, our realtor mentioned installing an attic fan instead.  Have you heard of these?   During the summer, the temperature in your attic can get well over 100 F.  Without an attic fan, heat gets trapped, and it makes your house warmer.  An attic fan helps cool down your attic, making your house much cooler.  IF you also happen to have A/C running, an attic fan improves efficiency; there’s less work required by your A/C unit to cool down the house.  I’ve read that it can save up to 30% on cooling costs, so in the long run, it may be cheaper for you to install one in your own home.

By the way, attic fans are electric or solar.  I think they may also come in hybrid versions but I haven’t seen any so far.  We’re thinking of installing the solar fan since no energy would be required to run it.  Now we just need to figure out where to buy one of these and who can install it.  Anyone have any recommendations?

Green is where the green is

I’m going to take a break from George W today. I need something positive to talk about. We all know the U.S. economy has slowed down. Unemployment is up, inflation is up, the stock market is down, earnings are down, and the pace of venture capital investment has slowed dramatically. We’ve seen dramatically fewer technology IPOs this year, and even the once “immune” technology sector is seeing the effects of the ailing economy.

One area bucking this trend is green technology. A United Nations report indicates over $148 billion was invested into alternative energy last year, up a whopping 60 percent from the $92.6 billion spent in 2006. The report describes this as a “green energy gold rush”. Wind energy led with $50 billion in investments, but solar was the largest gainer with a 90 percent rise, totaling $28 billion in investments. Even high profile venture capital firms such as Kleiner Perkins have established funds and partner areas earmarked for green investments.

What’s great is that this appears to be a global trend led by Europe, which as we all know is far more advanced from clean tech and alternative energy perspectives than the rest of the world. There appears to be strong and growing interest in emerging countries such as Brazil, China, and India as well, as these countries recognize their growth and development will soon be hindered by their consumption and dependence on foreign energy. In case you’re wondering, not only do we pollute the most in the U.S. (on both an absolute and per capita basis), but we are one of the worst, least advanced clean tech, developed countries in the world.

All green, all the time

planet_green_discovery_channel_logo

It was only a matter of time before this happened. Planet Green, the first and only (so far) 24-hour channel devoted to eco-friendliness just launched. Planet Green is part of the parent company that own the Discovery Channel, which I admit is one of my favorite channels. I never thought non-fiction television could be so compelling – and I’m not talking about “reality TV” folks.

Planet Green offers both television and online content focused around all things green. This includes not only tips and suggestions to help make your life more green, but also the latest green technology, how others are going green, and how you can detoxify your home and your lifestyle. As Planet Green says, it, along with TreeHugger.com, is helping to energize and move the green conversation into the spotlight.

There is a handy channel finder for you to located the channel it’s on in your area and with your particular subscriber. It’s even offered in HD quality if you want to be really blown away by green! They appear to have some great programming that I can’t wait to start watching.

Solar Incentive Program

solar-panels.jpgA new Solar Incentive Program recently passed in San Francisco. So if you live in the area, and you’re thinking about getting some solar panels, you may be able to take advantage of some financial incentives.

According to one of our favorite blogs, Inhabitat:

An annual budget of $3 million dollars will help create incentives for individuals and businesses to install solar photovoltaics systems with a $3,000 to $6,000 rebate available to individuals and a $10,000 rebate for businesses.

This site also has some good FAQs if you are seriously considering installing solar panels.

My kind of town, Chicago is…

chicago-skyline.jpgI lived in Chicago circa 1993-2004, during which most of this time I lived near Lincoln Park (Lakeview to be exact). I worked in downtown Chicago and would hop on the 151 (bus) everyday. I had my ups and downs with the 151 - it safely brought me to 333 East Wacker and back without fail, but was crowded and downright gross in the heat of the summer (picture your face being smashed into someone’s armpit when the bus lurched to a stop.) Yum. Regardless, I loved the freedom public transportation afforded me. The fact that I only used my car on the weekends is a total 180 from my life today, where I basically drive everywhere and everyday (public transportation in Mountain View, CA is sorely lacking in comparison). Anyway, there are other things I miss about Chicago - the food, the summer festivals, Ravinia, etc. I can go on and on.

Well here’s one more reason why Chicago is a great city: Mayor Daley. Regardless of your political party affiliation, you have to admit that he’s doing a pretty good job of making Chicago one of, if not the greenest cities in the US today. Here are just a few examples:

  • Chicago’s City Hall is the country’s first rooftop garden on a municipal building - Check out the Featured Projects link on this website
  • The Green Alley Project where alleys are retrofitted with environmentally sustainable road-building materials (there’s a lot more interesting information about this project here)
  • Museums (all of them) have been converted to partially run on solar power
  • All new public buildings to achieve at least LEED Silver status
