In my previous article on this topic, Solar Power Northwest: Remodeling your home, I looked at the numbers behind solar power in the Northwest prompted by two articles in James Lupori’s Kenmore Undressed blog. Now we’re going to take a look at an actual home in the Brier neighborhood, via James’ latest article: Solar Energy – The Perfect Remodeling Project of the Future, Part 3.
Eric’s setup uses 18 panels that provide most of his daytime power needs. The article doesn’t mention if Eric uses Energy Star appliances, which would benefit him by letting him sell power back to the utilities reducing his total utility bill. That’s the smart way to go.
[Edit: In response to the question about how much this installation cost Eric, I don’t have hard numbers, but I estimate it was between $28,000 and $30,000.]
The next step in energy conservation would be Smart Grid aware appliances, heating systems and water heaters.
The Smart Grid, in a nutshell, turns power transmission and production from a centralized system to a distributed system that is self-aware and responds to the demands for power from homes and businesses. This is supported by Smart Grid-aware appliances and heating and cooling systems in your home. As demand spikes, your fridge goes to a longer cooling cycle to reduce it’s load on the grid, your water heater doesn’t reheat the water immediately , etcetera. Ideally, your home will be wired to manage its energy usage. Instead of a water heater, you’d have an on-demand tankless water heater so there’s no need to heat or even store 30+ gallons of water.
However, creating the Smart Grid will take time. Puget Sound Energy is looking into implementing Smart Grid Technology, but like most nascent technologies, there are multiple standards coalescing into a single one. Just another step towards our energy independence!
