As 95% of Cololrado's electricity is currently generated from coal and natural gas...

...there is legislation in motion that will significantly increase your cost of that in the near future if it becomes enacted.

The problem is that my electricity is so cheap.......

Your power in Nebraska's is cheap because is currently mostly generated from coal and natural gas, but you also have two nuclear plants. Most all regional public utility commissions are mandated to require the regional utility companies to provide affordable, reliable power to their customers. Because of that, most electricity in this country is generated with carbon producing non-renewables (unless you have a siginificant nuclear power program in your area). Your "public power state" 16 cents per KwH is more that double that of 6 cents in Foomench's Colorado next door probably due to population density for the areas that each grid serves more than anything else.

It appears from the following report that the only renewable your state is pursuing in any significant quantity is wind power. We have experienced that having only 10% of our power produced by wind is already causing problems for the utility company - drops in wind speed can be sudden and it really screws up the frequency of the electrical grid as other generators can not react fast enough to come on line without some sort of "smart grid" technology that is more of a theory than a reality at the moment.

As most of Hawaii's fuel is imported from foreign countries (environmental regulations have all but eliminated the amount of domestic oil we used to import from Alaska), and with the rapid increase in oil prices we experienced last year, our governor and legislature have added language to the Public Utilities Commission to make long term energy security and locally produced renewable part of the consideration when approving power generation projects, even though it does cost more to the consumer to incorporate that as you mention.

The "cap and trade" carbon tax legislation is designed to drive up the price of the cheap power you currently enjoy so you are encouraged to switch over to renewables - either through your own actions or that which your utility company makes for you. Carbon taxes will not increase the cost of the electricity generated by nuclear power in your state.

Look's like Hawaii will soon implement "feed in tarriff"

http://pacific.bizjournals.com/pacific/ ... =printable

Essentially this opens the door and allows private renewable energy producers to be paid over the longterm more per kilowatthour than what it currently costs to burn fossil fuels. The rates have not been set yet, but as an example the utility company may decide to pay 0.30 per kilowatthour for domestically PV produced on a home even though it currently costs 0.24 kWh for imported carbon based electricity. That cost will be passed onto every one else that is still relying only on fossil fuel power.

Looks like California may be next, so you also could all be paying more for your electricity to help support the growth of renewable power without any new taxes or new government agencies sucking resources away with administrative costs to "manage" this shift. Allowing the existing Public Utility Commissions to pay more for renewable power and pass that cost on to everyone appears to be the fastest and most cost effective mechanism to achieve this.

If the fed and local governments continue to offer tax credits for PV and other renewables and stay out of selecting what type of renewable should be favored (i.e. ethanol), that is our best path to transition away from foreign energy dependance.

DAY 1 - Install panels

BEFORE - Solar Thermal collectors to left, remove chimney at right and relocate
Image

Install Rails for PV Panels
Image

Install PV Panels
Image

Connecting DC wiring to PV Panels
Image

Panels Installed, Solar Attic Fan Installed, Chimney Removed
Image

Inverter - This takes the DC generated from the roof and converts to 120v AC power that the house can use
If I make more power than I use, the extra goes out to the utility grid and it spins my meter backward
Image

DAY 2 - Wiring to follow................

Solar Home Brewery is up and running - my electric meter is spinning backwards when the sun is out!

A bit overcast today - curious to see how much is produced on a sunny day - it should make about 12kWh on a sunny day, we made 7kWh today, but the system was not turned on until 10 or 11am.

There is absolutely no wind today, but may play around with that in the future as well.
