The Environmental Benefits of LED Lights

Greenhouse gas emissions to Environmental Benefits

Greenhouse gas emissions are considered to be the primary reason for global warming.  The burning of fossil fuels and deforestation caused by humans increases the concentration of greenhouse gases such as carbon dioxide into the atmosphere. The average global temperature has increased by roughly 0.8 C/1.4F in the past 100 years. This may not initially sound like a big deal but a continuation of this could have very negative consequences for the environment and for us.

The rate of this temperature rise has progressed at a faster rate in the last 30 years with the majority of the 0.8 C increase occurring in this period. With developing economies such as China and India becoming new leaders in emissions, the situation can only get worse. Global warming would result in a rise in sea levels and more frequent occurrences of extreme weather. A change in the climate would also mean some areas are likely to experience droughts or flooding. There are methods that can dramatically reduce the amount of electricity we use and the amount of greenhouse gases released into the atmosphere.

One reason for the burning of fossil fuels is to meet our energy requirement for lighting. Lighting is one of the major contributors to energy consumption on our planet. Most people still use traditional types of lighting such as incandescent and fluorescent lights. These are very inefficient compared to a relatively new and upcoming technology, LED Lighting. There are the environmental benefits to using LEDs over fluorescents and incandescent lights, and they would help to cut down greenhouse gas emissions which heavily contribute to global warming.

One problem with lighting is the amount of energy wasted as heat, requiring more energy to light up. This is the case for common types of lighting such as fluorescents and incandescent which waste most of their energy on heat. However, this is not true with LEDs, which convert most of their energy to light and only a small percentage of energy is lost to heat. LEDs are up to 80% more efficient than fluorescent lights, for example a 36 watt LED can replace a typical 84 watt fluorescent.

The performance benefits of LEDs are also much better. Light can be distributed very evenly when used for purposes such as LED ceiling lights. This reduces the need for more lights to light up a certain area of a room, further reducing energy consumption. Decreasing our electricity use by switching to LED Lighting could massively decrease the total energy consumption in the world and is one of the essential factors in reducing greenhouse gas emissions.
