The nuclear accident at Fukushima should
have taught us that we need to drastically reduce the amount of energy
we use. It's time to stop thinking "bigger is better" and start
thinking "more efficient is better". It's not just an issue of
electricity use, so other areas of energy use are included here.
Here's some of the most
efficient products on the market.
Samsung has 32 inch TVs
that use between about 51 kWh/year (killowatt hours per year) and 57 kWh/year. These top the
Department of Energy's ENERGY STAR list.
Audio DTA-1 is so efficient it can run on AA
batteries, yet drive expensive audiophile speakers to very high
volumes. It can also be run
with the included
power supply. The Lepai
Tripath TA2020A+ Audio Mini Amplifier uses a similar
circuit, called a Tripath class D integrated circuit, but is smaller
and even more affordable. lots more Class D amps
The Raspberry Pi shows just how
energy efficient a computer can be. It can run on 4 AA batteries. It
opens up a whole world of possibilites for poor countries, as it only
Here's ten of the most
General Electric and Hotpoint have refrigerators that use only 300 kWh/year. Some models on the market use over 600 kW/h/year.
Electric bikes like those from Currie Tech use a fraction of the energy of a car.
Replacing an old dishwasher can save up to $40 per year on your electric bill. Here, Fisher and Paykel is tough to beat. They make models that use as little as 137 kWh/year.
Low rolling resistance tires don't use energy, but they save energy. Bridgestone has a calculator that shows how much money you can save.
is what professional mechanics use to clean out the carbon buildup in a
car's engine. But you can buy it too, and just pour it in the gas tank,
and increase your car's fuel efficiency.
This is the logical step up if you want
more power than the typical
Class D mini amp. Dayton is known for top value in amps and DIY
A-5VL A-5VL Integrated Stereo Amplifier This is a full size component so you
can stack it with your CD player and other components. Gary Altunian, a
reviewer for about.com, said the A-5VL "is designed for critical
listening and will reward you with a rich, detailed musical
experience". If I was in the market for an amp, this would be the one
I'd want. For anyone trying to live lightly on the Earth, but doesn't
want a mini sized amp, this is for you.
