Global Light Out

I was glad to hear that 30 million people switched off their lights for one hour on Saturday night. It was in response to global temperature warming. Fortunately, people all over the world were participating in the campaign by turning off their lights or dimming lights at public facilities. Google.com switched their background color to black from white. The homepage is colored in black. The message is that it is time for you to turn off your lights.

Carbon emission is causing a climate change of 1.4 degree in Celsius. One hour of turning off lights is not going to make a significant change. We need to change our lifestyle in order to keep the climate stable. I think public facilities should turn off the lights after 12 a.m. Just leave the street lights on. More effectively, hallways should install sound control lights.
In the long-run, in order to protect our earth, we need to stop using fossil fuel. Renewable energy is the way to go.

Technology has allowed us to produce energy from wind, water and solar. All of the renewable energy is environmentally safe without pollution. Statistics shows that 40 minutes of the sun’s light can produce enough energy to supply the earth for one year. Renewable energy can also be liquidized into fuel. It is expensive to invest in renewable energy. However, it is practical and profitable in the long run.
