Changing your source of electricity is one of the simplest and cheapest things you can do to reduce your footprint. Many utilities are offering “Green Power” options where a part of the electricity you use is purchased from more sustainable sources, for less than the price of a monthly LED bulb.
We live in the Pacific Northwest, and our power company here (Puget Sound Energy) offers a Green Power program where you pay a bit extra, in order to get a % of your electricity purchased from farm, biogas, and small hydro.
Why does it cost extra?
The extra cost is used as startup capital to encourage the creation of more small & renewable generation stations. In other words, your money will go into creating new independent businesses that will provide more renewable generation capacity in the region.
How do you know it is “your” electricity that is being generated?
There is no way to differentiate an electron from another. Technically, you are not buying their electrons, you are instructing your utility to buy more generation from them, proportional to your use, and place it in the grid.
Update. This was such a frequently asked question I made this other post: More Details on PSE Green Power.
How much difference does it make?
Power sources differ by region, but here in the Northwest the PSE “basic” offering comes from a pathetic combination of sources (the proportions are for 2011 data I could find)
- Large Hydro: 36%. Large hydro creates flood areas, change water tables, and disrupt natural flow of organisms along rivers.
- Coal: 32%. Burning coal pumps CO2 and other pollutants into the atmosphere. Earth requires less CO2 in the air to sustain humanity.
- Natural Gas: 30% Natural gas, another fossil fuel, pumps large amounts of carbon into the atmosphere.
- Nuclear & Other: 2% While nuclear is potentially a good “bridge” technology for a carbon crisis on earth, or super-specialized uses like biomedical and space exploration, it requires adult handling and our civilization is too immature yet to meet the long-term safety standards required by this technology.
- Wind Power: 50%. There are many generating farms in the region, especially towards the East where it’s windier.
- Landfill gas: 24%. I’m not a fan of this as it increases the profit margin of landfills, but if it’s there, you may as well use it.
- Low impact Hydro: 10%. Small hydro generation doesn’t require the big government subsidies, decades-long maintenance contracts, and large flood valley areas of large hydro.
- Biomass & Wood Waste: 7%. Burning wood waste instead of creating an acidifying pollutant by dumping chips. It’s popping back some CO2 into the atmosphere, but it’s from carbon that was captured in our geologic era.
- Livestock & Methane: 7%. Cows & their manure are a major source of greenhouse gases (GHGs). Capturing the methane for burning and producing power is smarter than farting it into the wind. I’m not a fan of supporting livestock industries, so increasing their profit margin is something I wouldn’t choose to do.
- Solar Power: 2%. The pacific northwest has high latitudes and a large part of it has a constant cloud cover, getting less than 150 Watts per square meter. The eastern region has higher solar exposure, however.
Is this the best I can do?
No, probably the best you can do is live on a farm or plant enough crops on your house or roof to then create alcohol that you feed into simple thermal generators or burn in lamps made of clay from your own garden. This would be a resilient, carbon-neutral, zero-supply-chain solution (except for the generator, if you buy it). It won’t run your microwave oven, however. Do what you can.
How do I do it?
1) Go to PSE.COM, log in or create your account.
3) Visit this page http://pse.com/savingsandenergycenter/GreenPower/Pages/For-Homes.aspx#form
4) Fill the form in and leave the “100 percent” option.There is NO rationale to choose less:
There is NO LOGICAL REASON NOT TO DO THIS!
