Led Lightings Solve The America Energy Crisis
- Aug 02, 2019-
The new energy crisis of the early part of the 21st century does not include such dramatic imagery, but it does have the potential to be an even greater problem if the world’s population continues to burn fossil fuels at the current rates and to pump greater amounts of carbon emissions into the atmosphere. To the extent that any cause-and-effect relationship between carbon emissions and future environmental problems is creating a new energy crisis, efficient LED lighting has the potential to take a large bite out of America’s and the world’s energy consumption and to reduce the overall carbon footprint created by artificial illumination.
One of the central elements of the new energy crisis is the inefficient consumption of electricity that is generated by coal-burning and other fossil-fuel driven power plants. Traditional artificial lighting converts approximately 10% of electrical energy input into light and wastes the remainder as excess heat. The United State Department of Energy estimates that switching from those traditional lighting sources to solid state LED lighting would reduce annual carbon emissions in the U.S. by more than 180 million metric tons over the next ten to fifteen years. To put this reduction into perspective, this transition would have the same effect as removing more than 38 million passenger automobiles from the country’s roadways. This conversion would not only substantially reduce greenhouse gas emissions, but it would also preserve fossil fuel resources for other uses until newer and cleaner energy sources are developed. The U.S. Congress has granted its imprimatur on these estimates with its mandate in the Energy Policy Act of 2005 for individuals and industry to adopt solid state lighting technology at a more rapid rate.
The conversion to LED lighting as a solution to the current energy crisis is not confined to the United States. Pakistan, for example, is facing an energy generation shortage of approximately 8,000 megawatts. Based on the objective reality that LED lights consume 50% less electrical energy than other artificial lighting sources, Pakistani authorities estimate that their country could save up to 5,000 megawatts simply by switching to LED lighting. That switch will also reduce the use of hazardous materials, including mercury vapor and other gases, that are incorporated into older lighting technologies.
The benefits of LED lighting are not limited to solving the modern energy crisis. With their improved efficiency and durability, LED’s help businesses and individuals to save money, and those savings can then be reallocated to more productive purposes. With no hazardous material usage in their production, LED lights reduce waste disposal problems at landfills. They also produce higher-quality light that facilitates more versatile and more easily-controlled lighting designs.
