Bernie Sanders believes that we must transform our energy system away from pollutive and dangerous fossil fuels, and towards energy efficiency and sustainability. Millions of homes and buildings need to be weatherized, and we need to greatly accelerate technological progress in wind, solar, and other alternative power generation. Bernie believes energy efficiency is crucial for cleaning up the planet, slowing global climate change, making the country more secure by gaining independence from foreign oil, and creating thousands of jobs. – http://feelthebern.org/bernie-sanders-on-energy-policy/
Hillary Clinton raised objections to fracking for oil and natural gas during the Democratic debate last night, saying the process would be substantially limited if she’s elected.
She would oppose hydraulic fracturing in states that do not want it and apply regulations to reduce methane emissions and protect water, Clinton said, emphasizing past statements.
“I don’t support it when any locality or any state is against, No. 1. I don’t support it when the release of methane or contamination of water is present. I don’t support it, No. 3, unless we can require that anybody who fracks can tell us exactly what chemicals they are using,” Clinton said.
“So by the time we get through all of my conditions, I do not think there will be many places in America where fracking will continue to take place,” she said. http://www.scientificamerican.com/article/clinton-would-limit-fracking-sanders-just-says-no/
Hydropower is electrical power generated utilizing the power of fast moving water. Rainfall or melted snow, normally originating in hills and even mountains, develop streams as well as rivers that eventually go to the ocean. The power of that moving water could be substantial, as any individual who has been whitewater rafting knows.
This energy has been made use of for centuries. Farmers since the old Greeks have used water wheels to grind wheat into flour. Positioned in a stream, a water wheel picks up flowing water in containers located around the wheel. The kinetic power of the streaming river turns the wheel and also is converted into power that runs the mill.
In the late 19th century, hydropower came to be a staple for generating the necessary electrical power to run machinery. One of the initial hydroelectric nuclear power plant was created at Niagara Falls in 1879. In 1881, street lamps in the city of Niagara Falls were powered by hydropower. In 1882 the world’s very first hydroelectric nuclear power plant began operating in the USA in Appleton, Wisconsin.
A common hydro plant is a system with 3 components: an electrical plant where the electricity is created; a dam that can be opened or closed to control water circulation; and a tank where water could be kept. The water behind the dam streams with an intake and also presses against blades in a generator, creating them to transform. The generator rotates a generator to create electrical energy. The quantity of power that can be generated depends upon how far the water decreases as well as just how much water actions with the system. The power could be delivered over long-distance electric lines to homes, factories, and also companies.
Hydroelectric power offers nearly one-fifth of the globe’s electrical energy. China, Canada, Brazil, the United States, and even Russia were the five largest producers of hydropower in 2004. Among the globe’s largest hydro plants is at Three Canyons on China’s Yangtze River. The reservoir for this establishment began completing 2003, yet the plant is not anticipated to be completely operational until 2009. The dam is 1.4 miles (2.3 kilometers) broad and also 607 feet (185 meters) high.
The greatest hydro plant in the United States lies at the Grand Coulee Dam on the Columbia River in north Washington. More than 70 percent of the electricity made in Washington State is created by hydroelectric centers.
Hydropower is the least expensive means to produce power today. That’s because when a dam has been built and also the devices mounted, the energy resource– moving water– is cost-free. It’s a tidy gas source that is renewable annual by snow and also rains.
Hydropower is additionally easily offered; developers could regulate the circulation of water via the turbines to generate electricity as needed. Additionally, reservoirs may supply recreational opportunities, such as swimming and boating.
But damming streams could damage or interrupt wildlife and even various other natural resources. Some fish, like salmon, may be avoided from swimming upstream to spawn. Technologies like fish ladders assist salmon increase over dams as well as enter upstream spawning areas, yet the presence of hydroelectric dams changes their migration patterns and also harms fish populations. Hydropower plants can also trigger low dissolved oxygen degrees in the water, which is damaging to river environments.

The United States could generate more than 10 times its power needs via wind power, among the fastest-growing energy resources. Turbines make use of wind to generate electrical power without developing toxins.
Presently, this is just one of the least expensive alternate energy resources offered. The obstacles to this resource’s appeal:
· Resistance to the towers that appear on the landscape. Many opponents consider the wind turbines to be unsightly and disruptive, yet these people ignore the more important benefits of the wind turbine’s existence.
· Concerns regarding the lasting influence of the towers and even generators on the habitat.
This makes use of moving water to move generators which create electricity. Hydropower gives 20 percent of the globe’s power demands, baseding on the USA Geological Survey.
There are numerous issues relating to the continued usage of hydropower:
· Rivers should be dammed, which can have an extreme influence on the land and also wild animals
· This impact also influences neighborhoods that rely on fish that needs to travel through the dams
· The expenses to develop these dams is huge, as well as the return is slow-moving
If all goes according to plan, our local star: The Sun, will be a source of energy for billions of years to come. The current modern technology to harness this power such as photovoltaic panels, solar collectors as well as thin-film solar sheet. The solar cells convert sunlight into electrical energy. There is no demand for a generator. It is a clean, non-polluting source of power.
The challenges that this renewable energy resource has consist of:
· Expense of the photovoltaic panels is still relatively high compared with other forms of power but with federal and local incentives, photovoltaic panel costs can be reduced greatly.
This is making use of warmed water and even steam from the Planet to run power stations, which transform the vapor right into power. California has greater than 40 geothermal power stations producing 5 percent of that state’s requirements. The Philippines, Iceland and even El Salvador are all creating greater than 25 percent of their electricity with geothermal plants.
Some of the obstacles with this energy resource are:
· Plants are pricey to create
· Place of the plants is limited to one of the most geothermally active locations
Biomass is the use of plants and even animal waste to develop power. When transformed effectively, it is a low-carbon resource of energy with little air pollution. A few of the challenges with this renewable energy consist of:
· This technology has not progressed as swiftly as wind and even solar, so it continues to be costly
· If not taken care of properly, it could have a damaging influence on the atmosphere
There are several motivations for discovering these alternatives as well as exactly how you may be able to utilize them in your house power plan, consisting of:
· They protect the environment from more damage
· They make use of resources that will not go out
· There are government incentives for executing renewable resource sources, as specified by the U.S. Department of Energy
