All of us use energy every day for entertainment, cooking, transportation, lighting, heating and cooling homes, manufacturing, etc. We consume a lot of energy. When energy is produced from non-renewable fuels, to heat our homes or power our cars for example, pollutants are released into the water and the air we breathe. The more energy we use or miles we drive in our cars, the more pollutants are released into the air.

Many of the environmental problems the world faces today – including climate change, air pollution, oil spills, and acid rains – result from our dependence on fossil fuels.  The burning of fossil fuels produces heat-trapping gases that are the main cause of the rise in global atmospheric temperatures.

The main way to save the energy, or, to say more correctly, to reduce the use of energy is recycling.

Aluminum

One of the most efficient forms of recycling is aluminum recycling. Aluminum can be reused repeatedly and requires very little processing to make it available for reuse. Manufacturers simply melt down crushed aluminum stock and add it to freshly extracted aluminum without any degradation of quality in the finished product.

Plastic

Seven major types of plastic are found in consumer products, and recycling can extend the use of most of them. Recycling plastic requires only a tenth of the energy needed to create new plastic from raw materials, according to Mike Biddle, president of MBA(Michael Biddle& Association) Polymers.

Paper

Recycling paper not only saves energy but also saves trees, reducing the amount of carbon dioxide present in the atmosphere. The EPA(Environmental Protection Agency) estimates that producing a recycled paper product requires only 60 percent of the energy required to create one from fresh wood pulp, and the Energy Administration Information reports that recycling a ton of paper can save 17 trees. Recycling paper also requires about half the water normally used in processing paper from virgin wood.

White Goat

Your office will never waste paper again with Oriental’s White Goat machine, which converts normal paper into toilet paper. Simply insert about 40 sheets of paper, and in 30 minutes you’ll receive a freshly made roll of toilet paper. The machine shreds the paper, dissolves it in water, thins it out and then dries it and winds it around a roll. According to Oriental, it costs about 12 cents to churn out one roll.

Glass recycling is less efficient than many other forms of recycling, due to the processing required to return glass to a usable, raw state. According to the EPA(Environmental Protection Agency), recycling glass only saves about 30 percent of the energy cost of producing new glass, and the raw materials required are in abundant supply. Reusing glass bottles and jars, however, requires no energy whatsoever, so you can reduce energy costs by finding new uses for these containers instead of simply throwing them out. Once you throw glass out, 1 million years will pass before that glass breaks down at the landfill.

Another way to save the energy is to use solar energy. Nowadays there are a lot of inventions that works using solar power. For example:

Weng Jie has designed a camera strap with integrated solar panels that will charge the battery in the camera.

“PlanetSolar” boat uses solar energy to travel around the world.

XOF1 solar car is an electric vehicle powered by 893 solar cells.

Lenses with solar panels collect energy to power electronic devices.

Modern grill uses mirrors to direct sunlight to the hot plate.

The Bedol water-powered clock is an inexpensive, ecofriendly machine. This innovative clock does not run on batteries or mains electricity but is powered only by water. The principle of fuel cell is used in this clock create an electrons’ flow from the water. You just need to put the water in the clock and a few drops of lemon juice in the reservoir and this clock will run non-stop for round 8 weeks. The clock features a built-in memory which keeps track of the time and you need not worry about resetting the time every time you change the water of this clock.

What can we personally do to save the energy?

Use fluorescent light bulb instead of light bulb:

When we use compact fluorescent lamp rather than regular bulb we can save energy by 60%. This simple change will save nearly 300 pounds of carbon dioxide a ye

Use less hot water:

When we want to heat water, it takes a lot of energy. We can decrease hot water usage by installing a low flow shower head and if we wash our clothes in cold or warm water instead of hot we can save 500 pounds per year. In the U.S., for example, if every family made this switch, they could reduce carbon dioxide by more than 90 billion pounds

Buy recycled paper products:

When we use that kind of products we can save energy from 70 to 90% and by that way, loss of forests are prevented all over the world.

Turn off electronic devices when we are not using them:

Simply turning off our television, computer, DVD Player when we are not using them will save us thousands of pounds of carbon dioxide a year.

Unplug electronics from the wall when we’re not using them:

It is not enough only to turn off tools like hairdryers, cell phone charges and televisions, because they still use energy when they are plugged in.

Plant a tree:

Just a single tree absorbs one ton of carbon dioxide during its lifetime, so planting a tree will be suitable also for next generation to live on healthy conditions.

Change your travel behavior, think more in terms of public transportation, if possible, walk or ride your bicycle instead of taking the car.

As conclusion, we should take part in the Earth Hour event. It will increase awareness to us about the climate change to reduce the carbon footprints. By switching off for at least one hour, we can help ease pollution such global warming, overuse the energy and air pollution. Actually, the Earth Hour cannot solve all the ills of the environment, but let it be our resolve to heal the environment. Prevention is better than cure.
