Case Study

Clean Energy

Power generation is a leading cause of air pollution and the single largest source of the world’s global warming emissions. Coal is the worst offender, a dirty energy source that produces less than half our electricity but nearly 80 percent of all power plant carbon emissions.
The good news is that coal is on the decline. Many old and inefficient coal plants are closing down and essentially no new coal plants are being built in the world, a trend that is driving the largest transformation of the world’s electricity system in half a century.
The energy choices we make during this pivotal moment will have huge consequences for our health, our climate, and our economy for decades to come.
Right now we are moving toward a natural gas-dominated electricity system, but an over-reliance on natural gas has significant risks and is not a long-term solution to our energy needs. Like coal, it is a fossil fuel that generates substantial global warming emissions, and has other health, environmental, and economic risks.
There’s a better, cleaner way to meet our energy needs. Solar is a renewable energy source that generates electricity with literally no pollution and global warming emissions—and could reliably and affordably provide up to 40 percent of the world’s electricity by 2030, and 80 percent by 2050

To create a cleaner, safer, affordable and healthier energy future, it’s time to choose renewables like solar first.


Energy Savings

Efficient energy use, sometimes simply called energy savings, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve and maintain a comfortable temperature. Installing LED lighting reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs. Light Emitting Diodes use one-third the energy of incandescent lights and may last from 6 to 10 times longer. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production processes or by application of commonly accepted methods to reduce energy losses.
There are many motivations to improve energy efficiency. Reducing energy use reduces energy costs and may result in a financial cost saving to consumers if the energy savings offset any additional costs of implementing an energy efficient technology. Reducing energy use is also seen as a solution to the problem of reducing carbon dioxide emissions. According to the International Energy Agency, improved energy efficiency in buildings, industrial processes and transportation could reduce the world’s energy needs in 2050 by one third, and help control global emissions of greenhouse gases.
Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy. In many countries energy efficiency is also seen to have a national security benefit because it can be used to reduce the level of energy imports from foreign countries and may slow down the rate at which domestic energy resources are depleted.
