Congress passed law 2016 mandating bulbs

But the rating only describes how much of the electricity input they turn into power; it does not reflect how much of the original, primary energy is lost in generating the electricity in the first place and then getting it to the motor.Efficiencies of heat engines can be improved further, but only to a degree.The chemical energy in the gasoline is converted to heat energy, which provides pressure on the pistons.That mechanical energy is then transferred to the wheels, increasing the vehicle’s kinetic energy.

Some biodiesel is also produced from used oils or fats, including recycled restaurant grease.

Today, technology can filter out 99 percent of the tiny particles and remove more than 95 percent of the acid rain pollutants in coal, and also help control mercury.[101] [102] * Since the late 1970s, new automobiles have been equipped with catalytic converters, an “anti-pollution device” that converts “exhaust pollutants …

to normal atmospheric gases such as nitrogen, carbon dioxide, and water.”[104] [105] [106] * Biofuels such as ethanol generate CO2 when burned, but the crops used to make these fuels absorb an equal amount of CO2 as they grow.

Most energy on earth ultimately comes from the sun, and this energy typically undergoes multiple conversions before it is used to accomplish a particular task.

For example, the energy that ultimately powers a light bulb may have the following history: Every time energy changes forms, some portion is “lost.” It doesn’t disappear, of course. That is, there is exactly as much of it around after something happens as there was before.

This time cannot be spent in producing things that can be sold, working on the land, or learning. The rest show generation measured as a portion of total U. * When modern energy is unavailable or expensive, people tend to burn more wood, crop waste, manure, and coal in open fires and simple home stoves.
