There are almost endless reasons why clean energy is and could be important to our future, but here are some of the most important:

Renewable energy can play an important role in U.S. energy security and in reducing greenhouse gas emissions. Using renewable energy can help to reduce energy imports and reduce fossil fuel use, which is the largest source of U.S. carbon dioxide emissions.

Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike.

• Global health will improve.
• Fewer floods and droughts will occur.
• Renewable energy sources like wind power promote economic growth.
• Clean energy sources create jobs.

Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.

Their average costs are $37/MWh and $40/MWh, respectively. By comparison, combined cycle gas turbine (CCGT) plants come in at $56/MWh and coal at $92.5/MWh. Large-scale hydroelectric programs produce electricity at about $40/MWh. The cost of electricity from the other renewables is coming down year-on-year.

Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels.

One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity.

: usable power (such as heat or electricity) that comes from a renewable or green resource alternative energy sources/technology.

Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth. Our energy choices and decisions impact Earth’s natural systems in ways we may not be aware of, so it is essential that we choose our energy sources carefully.

When we talk about residential uses of energy, these are the most basic uses of energy. They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking.

Energy fuels your body’s internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body’s most important nutrient, helps facilitate the chemical reactions that produce energy from food.

10 Household Items That Use More Energy Than You Think

• Clothing iron. Ironing your clothes may not take much of your energy, but the iron itself will use around 1,200 watts per hour.
• Hair dryer.
• Humidifier.
• Toaster oven.
• Coffee maker.
• Vacuum cleaner.
• Microwave.
• Dishwasher.

Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal and natural gas — and renewable sources like wind, solar, geothermal and hydropower.
