why do we need to conserve energy
Why Do We Need to Save Energy? You've probably heard the grown-ups in your house say "Turn off the light! " or "Close the refrigerator door! " Have you ever wondered why? Energy is there whenever we need it, so it's easy to forget where it comes from, or how much it costs. It all adds up Every year, we use more energy than we did the year before. In fact, the amount of energy Americans use has doubled about every 20 years. All of that energy adds up, and much of it is wasted by using too much or not using it wisely. Energy isn't free. The grown-ups in your house pay for the all the electricity you use. So wasting energy is the same as wasting money - and we know that's not a good idea! Wasting energy isn't good for the environment either. Most of the energy sources we depend on, like coal and natural gas, can't be replaced - once we use them up, they're gone forever. Another problem is that most forms of energy can cause pollution.
How you can help It might seem like kids can't do much to help. But every time you turn off a light bulb or close the refrigerator door, you're saving energy. You can also help by reminding grown-ups to turn the heat down in the winter, buy energy-smart light bulbs and use appliances the right way. There are lots of easy ways to save energy at home - and all those energy-savers add up to a big impact on the environment. To get started, try the. The grown-ups in your house can help! Then you can test your energy smarts by visiting our.
We all know that itвs important to save energy. In fact itвs been impossible to ignore the headlines telling us to do our bit for the environment, reduce our carbon footprint, adopt a greener lifestyle, and so on. But how many of us know the hard facts as to why we need to change our ways, and why saving energy is so important?
We need to motivate ourselves into becoming more efficient with the way we use energy in the home, at work and in our everyday lives. Understanding the full picture will help kick-start better energy habits sooner. Every time we perform the simplest task that uses energy - from making a cup of tea to turning on the TV в the natural resource used to create that energy becomes further depleted. And once itвs gone, itвs gone. Fossil fuels, which we depend on to power the UK, are a finite source of energy and will run out sooner than many of us realise. According to the World Wildlife Federation (WWF), renewable energy provides only 2. 7 per cent of UK electricity and less than one per cent of overall energy use. That means that fossil fuels are more precious than ever until we resolve the problem of our reliance on them. Worryingly, industry experts predict that current oil reserves will only last another 40 years, and coal another 200 years at most в and thatвs only if we carry on using energy at the rate we currently are.
At the same time as stripping the planet of its natural resources, our energy consumption is also drastically affecting its climate patterns. Each time a fossil fuel is burned, CO2 is released during the process into the atmosphere, changing the Earthвs natural climate and weather systems. While of course long hot summers and heat waves can be a welcome change to the usual wet weather in the UK, flooding, diminishing ice caps, droughts and extreme weather conditions around the world arenвt so desirable. Here are some more startling predictions of what changes to climate could cause, and how weвll be affected: Exposure to higher levels of UV light could cause an extra 5,000 deaths a year from skin cancer Over a quarter of the CO2 produced in the UK comes from the fuel we use in our homes, so cutting the amount of energy each of us use would have a major impact.
The WWF has called for a cut of at least 60 per cent in carbon dioxide emissions by 2050. So far, the UKвs commitment to saving energy has been more talk and less action. The government set the goal of cutting carbon dioxide emissions by just 20 per cent from 1990 levels by 2010, but are likely to fall well short of their targets. In fact, carbon dioxide emissions have recently risen due to the rise in the price of gas, meaning more coal (which produces the greater amount of CO2) being burned instead. And with the global economies of China and India booming, the amount of energy used in the world as a whole looks set to escalate further. Itвs easy to see why saving energy has taken main stage on the national and world agenda. And more than ever, thereвs no excuse for not doing something about it.
