Rebuilding Haiti: Solar Power Essential

- Adam Clare

Repairs and rebuilding has been going on in Haiti after the powerful earthquake hit the country about two weeks ago. They aid teams have run into a problem around energy – there’s not enough diesel. Things that rely on solar power are still working – bizarrely the traffic lights are on such thing. The good news that comes from all of this is the revived interest in renewable power for disaster recovery.

We can all benefit from this research into renewable energy sources for disaster recovery.

Solar setups are quick to install, mobile, and relatively inexpensive compared to the price of rebuilding a damaged electricity grid. They can also be incredibly robust. Alan Doyle, a science editor at MSNBC, recently wrote that a single solar water purification system, recovered from the rubble by the Red Cross, is now purifying 30,000 gallons (over 110,000 liters) of water a day.

Sol Inc, a US-based solar street lighting company, has sent a first shipment of lights for roadways, food distribution, and triage sites. This may sound mundane, until you imagine trying to perform street-side surgery or find family members in the dark. The LED lights can also withstand hurricane force winds – no small thing in a country that has also recently been hit by tropical cyclones. Sol Inc has promised to match donations for people wanting to contribute to the program.

Communications are another crucial need being met by solar. China’s ZTE corporation has donated 1,500 solar cellphones and 300 digital trunking base stations. The same technology was used in China when an earthquake hit the Sichuan Province in May of 2008. A similar project is being set up by a group from Holland.

Renewable energy in Haiti is not a new. Walt Ratterman, CEO of non-profit SunEnergy Power International was working on the electrification of Haitian hospitals at the time of the quake. He is currently still missing.

Six Good Things That Pay for Themselves

- Adam Clare

Being a little greener and a little richer is really easy with these six items that pay for themselves within a year by helping the environment.

5. Programmable Thermostat
Having a programmable thermostat is the easiest way to lower your heating and cooling costs. And having the house temperature right where you want it every hour of the day isn’t bad either. You can find programmable thermostats as cheap as $20 – at that price, it would probably pay for itself many times over in a year.

Conserving Energy Starts at Home

It goes without saying that saving energy is a good thing, and it’s something that everyone can do. It’s really easy to save energy and sometimes it’s easy to forget how easy it is, luckily the internet is filled with tips on how to save energy at home.

2. Make sure that the rooms in the house are neither too cold nor too warm.
Heating and cooling systems takes up most of the energy which is being consumed by a typical household. By making sure that each individual room in the house has just the right temperature, you will be saving a lot on CO2 emissions.
3. Make sure that the air filters are cleaned and the heaters are well-insulated.
Again, heating and cooling takes up most of the energy consumption in a typical home. When you see to it that your air filters are cleaned or replaced regularly, the energy will not be lost. Dirty air filters need to work doubly hard and take twice as much energy to work properly.
The same thing applies when you make sure that the heaters are well-insulated – it’s a good way to observe that no heat is escaping and you’re not using any more energy than you have to.

Make Your Telecommute Even Greener

- Adam Clare

Telecommuting is good for the environment because it means that people don’t have to get in a car and not move during rush hour. Granted they can take transit or bike, but some people like the “freedom” of getting into slow moving roadways. Telecommuters have it even better because they can wear slippers and pajamas all day.

Over at Web Worker Daily, they recently asked readers how to make web working more green.

I don’t claim to have all the answers, but there are a few areas that seem to be obvious candidates for a web worker focus. Energy consumption is one: if we swap cars for more computers, our carbon footprint doesn’t go down as much as it might. We’ve looked at cutting down on vampire power as a way to attack this in the past. Virtual machines can also offer computer – and power – savings.

Google to Make Solar Energy Cheaper than Coal

Google logoGoogle is at it again, we’ve covered Google quite a bit, more than any other company I think. It’s just so nice to see a company with billions of dollars at their disposal directing their energy at improving the world (and yes, I know that Google is nowhere near perfect and Sun is more the environmentally friendly tech company).

This time around they are contuning their solar power drive by investing in companies that will encourage the use of renewable energy. They emphasize solar power, but they are not limiting the hundreds of millions of dollars they want to invest in solar power.

“Our goal is to produce one gigawatt of renewable energy capacity that is cheaper than coal. We are optimistic this can be done in years, not decades,” Larry Page, Google’s co-founder and president of products, said in a statement.

One gigawatt can power a city the size of San Francisco.

Google is seeking to capitalize on the recent excitement among Silicon Valley entrepreneurs to apply the risk taking that computer, biotech and Internet businesses are famous for to the field of alternative energy production.

Google’s latest moves come as the price of a barrel of oil nears $100 and coal, which produces 40 percent of the world’s electricity, faces regulatory and environmental pressures that could drive up prices.
