From the darkness comes the light?

Earth Hour is approaching; On Saturday night we're going to shut off the lights between 8:30 and 9:30 PM. This will signal our vote for action against climate change. Now I must first mention that I would consider myself to be an environmentalist. However, I see this one hour as more like a statement than an actual call for change. How many people will continue to shut off all the power in their homes every night at 8:30? How many will install programmable thermostats and buy energy efficient light bulbs? Would it not make more sense to have a statement that will result in lasting change? Like Energy Efficient Bulb Day where you must turn off all the lights in your home that do not use energy efficient light bulbs. Then the lights on would make a statement. When this day is over, most will go back to their old energy wasting ways, and realistically, why shouldn't they? A normal family cannot live in the dark everyday, so what does a one hour power outage really tell us about our energy use? People need to have their eyes opened to how small changes that they make in their everyday choices can impact the planet. Encouraging them to make a change that will make a difference seems like a much more valuable use of time and resources that asking them to make a statement that will not yield tangible results. I can't help but wonder... how many of us will continue to live in the dark once the lights are turned back on?
