The five disadvantages of solar power


It's intermittent. Solar energy is only available when the sun is shining.

It's low efficiency. It requires large areas of land.

It's not completely free of environmental impact. Ultrapure polysilicon is now scarce.


It's high cost.


You must climb your roof to wash it off. Just ask Ed Begley, Jr.!

What leading edge developments should I be focusing on?

You woke up this morning full of vim and vigor, ready to tackle the world of home energy efficiency. Of course, your first dreamy thoughts were: is this major solar flare going to knockout electricity in the midwest power grid, and then, if Fermilab has found proof of the Higgs Boson, will I be able to fully explain the phenomena of convection and chimney effect to people? After your morning coffee, the reality check sets…

Yes, Virginia, you can save money on fuel!

It really wouldn't be fair not to share this timely report, which was aired in major cities last night:

http://philadelphia.cbslocal.com/2012/03/05/3-on-your-side-one-penny-home-heating-oil/

It describes a buying program which resembles other rewards programs. The website is called Neighbor Oil. They offer discounts on oil and propane, based on a points system.…

How will people afford to heat their homes?

Fuel poverty, that is to say people who can't afford to heat their homes, is at all time high levels in the U.S., Canada, and the U.K. It causes at times a terrible human condition, death, which is estimated as 8,000 people per year in the U.K. There have been calls for immediate "super energy efficiency." No doubt the rest of the world is affected, also.

Heating oil prices in the U.S. are topping $4.11/gal(up), propane $2.90/gal(up), natural gas…

Accuweather's secret home energy efficiency function...

... shhh, don't tell ! I recently ran across this functionality on Accuweather, after doing a google search for something or other:

http://www.accuweather.com/en/us/new-york-ny/10007/home-energy-efficiency/349727

If you click on the about button, you essentially get a zero explanation. Monitoring it for several days, it seems to prioritize sunniness, then temperature, then who…

Why people don't change their electrical supplier!

It's inexplicable as to why people are sluggish or fearful in regards to getting a better rate on their electric supply rate! 

Only 2% of people were thinking of changing their electricity or gas supplier, down from a third who were interested before the market was opened up statewide in 2006.

The study and recent survey also looked at how many people had already changed suppliers – just 2% for gas and 3% for electricity. You might almost call…

Manual Thermal Control Is Always Best!



  

The finer points of thermostats are actually much more complicated than any published article covers. You must study each premium thermostat individually. If it does not have settings for swing, deadband, fan delays, early recovery, proper setbacks, etc., it's not really of good use. Dual fuel setups are even more complicated because you must decide whether to use the thermostat or the fossil fuel controller function for balance point control. You must also…
