We're in the middle of a multi-year drought and the power company is calling a 'flex-alert' for tomorrow in anticipation of there being a power shortage here in SoCal due to the heat, which is not helping our drought situation. Efficient lightbulbs and low-flow toilets are just part of what is needed if we're going to maintain anything close to our current lifestyle.
In our case, in the last 3 years we've replaced all our our windows with dual pane, low-emissive glass. Replaced virtually all of our incandescent lights with CFL's or LED's (actually we're about 90/5/5 LED's to CFL's to incandescent). Replaced our toilets with dual-flush, low-flow models. And most recently purchased new a HE (High Efficiency) washer and dryer pair. As well as taking other energy saving measures. We also allow the power company to remotely cycle our AC unit in case of a pending power shortage.
We all need to do our part.
