Fight against Global Warming - Start by making small chnages , its easier than you think.
Let's start with a no-cost step. About 75 percent of the energy consumed by home appliances occurs while they're turned off but still plugged in. Unplug everything in your house that doesn't need to be connected full-time, or plug cords in to surge protectors, which can be flipped on as needed.
Curb Your Temper(ature)
Every degree you lower the thermostat in winter and raise it in summer can reduce your heating and cooling bills by 1 percent or more. Install an automatic, programmable thermostat that allows you to set specific temperatures for different times of day. For example, in winter you don't need it as warm when you're sleeping, and in summer you don't need to cool the house while you're at work. While on the subject of temperature, make sure your water heater is set at the mid-range of 120 degrees; anything hotter and you're wasting energy. And if your water heater is at least three years old, wrap it in an insulation blanket (newer models are better insulated), and will save enough energy to prevent the release of up to 1,000 pounds of carbon dioxide, as per climatecrisis.
No Pane, No Gain
Replacing single-pane windows with energy-efficient double panes can reduce your heating and cooling needs by close to one-third.
Go with the (Low) Flow
A low-flow showerhead—which uses less hot water—can reduce carbon-dioxide emissions 376 pounds and lower your utility bill annually.
About a quarter of the energy needed for our homes goes toward keeping on the lights. If a household replaced one traditional lightbulb with an energy-efficient compact fluorescent lamp (CFL), we would save $600 million in utility bills and enough energy to light 3 million homes each year. CFLs cost more, but they use nearly 75 percent less energy and last about 10 times longer than incandescent lightbulbs.
Erase Your Footprint
If you can't afford to convert every square foot of your home into a paradigm of energy efficiency—and let's face it, very few of us can—then try the next best thing: Purchase carbon offsets. For every pound of carbon dioxide your home releases, you can fund an environment-friendly endeavor that reduces the amount of greenhouse gases released into the air.
