earth, the final frontier

Clean Energy, Clean Environment

We are at a cross roads in human history, we can choose to continue on as we have been, or we can make a change to improve our future and quite possibly the future for several generations to come. We are here to promote energy independence, a better environment, a secure future and a higher return on investment for your hard earned dollar. It is what I believe in, it is why I am in the solar business.

New York A7557A fixes some of it’s net metering law

30 Jul 10 | Solar Electric, Wind Power

New York legislature has fixed at least one issue with the net metering law (PSL 66) with A7557A, which was signed by the Governor last March.  The law took effect yesterday.  Here are some of the issues addressed:

  1. Removed the requirement that solar generating equipment not exceed customer’s peak load.
  2. Removed the requirement that wind generating equipment not exceed customer’s peak load.
  3. Make certain provisions for commercial customers to pay for the installation of safety equipment

Increasing solar and wind generating capacities are a step in the right direction.  If a customer has a resource that is available to be used to generate power for other electrical customers, there is no reason not to take advantage of it.

The utility companies buy this power at wholesale rates and sell it for retail to the next few customers down the line.  Everyone wins.

This is Solar Power, Part I

06 Jul 09 | Commentary, wind power

A review off all the energy systems powered by our sun, either directly or indirectly.

Part I: Wind Energy

Wind Energy is derived from the sun due to uneven heating of the earth’s surface.  This creates pressure gradients.  Because nature abhors a vacuum, air from high pressure areas moves toward areas of lower pressure.  From Wikipedia:

It is estimated that the total amount of economically extractable power available from the wind is more than present human power use from all sources.[12] An estimated 72 TW of wind power on the Earth potentially can be commercially viable,[13] compared to about 15 TW average global power consumption from all sources in 2005

Renewable: Yes
Environmental impact: Moderate
EIER: Moderate to high
Cost: Moderate
Maintenance cost: Moderate

Here are two videos of wind turbines in Portsmouth, RI.  These units are located about 2 miles apart, one was installed in 2005, the other in 2009.  The wind at ground level was low, but you would not know it watching these things turn:

Portsmouth Abbey, Vestas V-47 660 KW

Portsmouth High School, AAER A-1000S 1 MW:

The Vestas unit turns faster and is a little louder. They both look really cool, however, and both schools are saving a lot of money.
