Question

why do we need efficient and environment - friendly technologies​

Answer 1

Answer:

Eco-Friendly Technologies

Jack, from Green Tech box, defines a green or eco-friendly technology as a technology that has no net adverse affect on the environment and uses a sustainable source of energy. These eco-friendly technologies have been more and more commonplace since they are not only a benefit to the environment, but they can also be a benefit to the consumer as well. Some other characteristics of eco-friendly technologies are:

Recycled or reused materials

Reduction of greenhouse gas emissions and pollutants

Use of renewable energy and minimal use of natural resources

Low consumption and low-impact

Here are some examples of mainstream eco-friendly technologies:

Hybrid & Electric Cars

Hybrid and electric cars are an example of more common eco-friendly technologies. Hybrid cars use a combination of a normal combustion engine and an electric motor in order to cause a very fuel efficient car. Electric cars are completely electric and do not produce any greenhouse gas emissions. Although hybrid cars are very common now in the United States, electric cars are finally starting to hit the mainstream with eco-friendly states such as California rapidly implementing the type of infrastructure needed in order for electric cars to be commonplace. These eco-friendly cars save energy and greatly reduce the amount of greenhouse gas emissions.

Lighting

Another eco-friendly technology that has become mainstream is highly efficient LED lighting. Incandescent light bulbs, the types of light bulbs that were used for the past 50 years, are very inefficient with 98% of the energy that they produce being output as heat. However, new eco-friendly LED light bulbs can use 160 watts to replace a 400 watt lamp and still produce the same or a greater amount of light. These light bulbs can produce a 90% reduction in energy consumption, causing an enormous amount of energy savings and benefits to our environment!
