> MEASURES TO REDUSE GREEN HOUSE EFFECT ON EARTH

One of the best ways to reduce greenhouse gas emissions is to limit energy consumption. Using energy in many of its forms comes with the negative externality of releasing greenhouse gases into the atmosphere.

# For instance, electricity is commonly produced by coal power plants which burn goal and release CO2 into the air. Limiting the use of devices which use fossil fuels for energy is especially important cars, lawn mowers, chainsaws, and other gasoline and diesel powered devices account for a large portion of the greenhouse gasses emitted by humans.

# Finding clean energy alternatives is a good way to limit the greenhouse effect while still getting the energy you need. Efficient hybrid cars and green electricity sources, such as solar and wind power, help reduce greenhouse emissions.

*USE LESS ENERGY

#Taking steps to use less electricity, especially when it comes from burning coal or gas, can take a big dent out of greenhouse gas emissions. Worldwide, electricity use is responsible for a quarter of all emissions.

#Some steps that you can take to use less electricity are simple and save money – like replacing incandescent light bulbs with LED bulbs that use less electricity, adding insulation to your home, and setting the thermostat lower in the winter and higher in the summer, especially when no one is home.

#There are also new technologies that help keep buildings energy efficient, such as glass that reflects heat, low-flow water fixtures, smart thermostats, and new air conditioning technology with refrigerants that don’t cause warming. In urban and suburban environments, green or cool roofs can limit the amount of heat that gets into buildings during hot days and help decrease the urban heat island effect.

*Generate electricity without emissions

Renewable energy sources include solar energy, geothermal, wind turbines, ocean wave and tidal energy, waste and biomass energy, and hydropower. Because they do not burn fossil fuels, these renewable energy sources do not release greenhouse gases into the atmosphere as they generate electricity.

#Nuclear energy also creates no greenhouse gas emissions, so it can be thought of as a solution to climate change. However, it does generate radioactive waste that needs long-term, secure storage.

#Today, the amount of electricity that comes from renewable energy is growing. A few countries, such as Iceland and Costa Rica, now get nearly all of their electricity from renewable energy. In many other countries, the percentage of electricity from renewable sources is currently small (5-10%) but growing.
