Renewable Electricity Standards Are a Smart Climate Solution

With only five percent of the world population, the United States produces nearly 25 percent of annual global heat-trapping emissions. Electricity generation accounts for fully one-third of these emissions.  We have a responsibility and a compelling interest to significantly reduce these harmful emissions. Renewable electricity standards offer a smart, affordable climate solution with a proven track record.

Placing planet Earth on a strict diet—100 percent renewable energy—can be done by 2050, without the need for radically new technology, contends Stanford University Professor Mark Z. Jacobson.

The path to a world powered by wind, water and sunlight is, in fact, decidedly low tech, Jacobson says. Storing heat in underground rocks. Making mounds of ice at night, when electricity is cheaper, and melting it for air conditioning during the day. Building wind turbines on and offshore.
But Jacobson’s team in Stanford’s Atmosphere/Energy program is moving far beyond this simple vision of a clean power world. His research group uses sophisticated modeling to develop tailored energy plans that would allow a smooth transition to renewables in all 50 U.S. states, as well as 139 countries, by 2050. He helped co-found a non-profit, “The Solutions Project,” that disseminates these plans and educates the public and policy makers about them.

On a break during a recent visit to NASA’s Jet Propulsion Laboratory in Pasadena, Jacobson described his initiative.

Improved Public Health and Environmental Quality

Generating electricity from renewable energy rather than fossil fuels offers significant public health benefits. The air and water pollution emitted by coal and natural gas plants is linked to breathing problems, neurological damage, heart attacks, and cancer. Replacing fossil fuels with renewable energy has been found to reduce premature mortality and lost workdays, and it reduces overall healthcare costs . The aggregate national economic impact associated with these health impacts of fossil fuels is between $361.7 and $886.5 billion, or between 2.5 percent and 6 percent of gross domestic product (GDP).

Wind, solar, and hydroelectric systems generate electricity with no associated air pollution emissions. While geothermal and biomass energy systems emit some air pollutants, total air emissions are generally much lower than those of coal- and natural gas-fired power plants.

In addition, wind and solar energy require essentially no water to operate and thus do not pollute water resources or strain supply by competing with agriculture,

drinking water systems, or other important water needs. In contrast, fossil fuels can have a significant impact on water resources. For example, both coal mining and natural gas drilling can pollute sources of drinking water. Natural gas extraction by hydraulic fracturing (fracking) requires large amounts of water and all thermal power plants, including those powered by coal, gas, and oil, withdraw and consume water for cooling.

Biomass and geothermal power plants, like coal- and natural gas-fired power plants, require water for cooling. In addition, hydroelectric power plants impact river ecosystems both upstream and downstream from the dam. However, NREL's 80 percent by 2050 renewable energy study, which included biomass and geothermal, found that water withdrawals would decrease 51 percent to 58 percent by 2050 and water consumption would be reduced by 47 percent to 55 percent .

A Vast and Inexhaustible Energy Supply

A Vast and Inexhaustible Energy Supply

Around the world, strong winds, sunny skies, plant residues, heat from the earth, and fast-moving water can each provide a vast and constantly replenished energy resource supply. These diverse sources of renewable energy have the technical potential to provide all the electricity the nation needs many times over.

Estimates of the technical potential of each renewable energy source are based on their overall availability given certain technological and environmental constraints . In 2012, NREL found that together, renewable energy sources have the technical potential to supply 482,247 billion kilowatt-hours of electricity annually (see Table 1). This amount is 118 times the amount of electricity the nation currently consumes. However, it is important to note that not all of this technical potential can be tapped due to conflicting land use needs, the higher short-term costs of those resources, constraints on ramping up their use such as limits on transmission capacity, barriers to public acceptance, and other hurdles.

Source:  “U.S. Renewable Energy Technical Potentials: A GIS -Based Analysis”, National Renewable Energy Laboratory. July 2012.
Today, renewable energy provides only a tiny fraction of its potential electricity output in the United States and worldwide. But numerous studies have repeatedly shown that renewable energy can be rapidly deployed to provide a significant share of future electricity needs, even after accounting for potential constraints .

Little to No Global Warming Emissions with the wind solar energy

Human activity is overloading our atmosphere with carbon dioxide and other global warming emissions, which trap heat, steadily drive up the planet’s temperature, and create significant and harmful impacts on our health, our environment, and our climate.

Electricity production accounts for more than one-third of U.S. global warming emissions, with the majority generated by coal-fired power plants, which produce
approximately 25 percent of total U.S. global warming emissions; natural gas-fired power plants produce 6 percent of total emissions . In contrast, most renewable energy sources produce little to no global warming emissions.

According to data aggregated by the International Panel on Climate Change, life-cycle global warming emissions associated with renewable energy—including manufacturing, installation, operation and maintenance, and dismantling and decommissioning—are minimal .

Compared with natural gas, which emits between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour (CO2E/kWh), and coal, which emits between 1.4 and 3.6 pounds of CO2E/kWh, wind emits only 0.02 to 0.04 pounds of CO2E/kWh, solar 0.07 to 0.2, geothermal 0.1 to 0.2, and hydroelectric between 0.1 and 0.5.

Renewable electricity generation from biomass can have a wide range of global warming emissions depending on the resource and how it is harvested. Sustainably sourced biomass

has a low emissions footprint, while unsustainable sources of biomass can generate significant global warming emissions.

Increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce U.S. global warming emissions.

For example, a 2009 UCS analysis found that a 25 percent by 2025 national renewable electricity standard would lower power plant CO2 emissions 277 million metric tons annually by 2025—the equivalent of the annual output from 70 typical (600 MW) new coal plants . In addition, a ground-breaking study by the U.S. Department of Energy's National Renewable Energy Laboratory explored the feasibility and environmental impacts associated with generating 80 percent of the country’s electricity from renewable sources by 2050 and found that global warming emissions from electricity production could be reduced by approximately 81 percent.

What is off grid wind solar system?

People are interested in off-grid power for a variety of reasons. Some build a house so far from the power lines that wind and solar power is the economical option. Others make a conscious decision to break their grid-addictions and live a simpler, less complicated life. But most just want an option.

This is not your daddy’s USA, and not all of the changes are for the better. We have grown so dependent on the grid that life may not be sustainable without it – unless you have options. Think about it. Everything you need to sustain life; water, food, heat, cooling, transportation, and fuel, depend on the electric distribution system. Even the response of fire fighters, law enforcement, and emergency medical personnel will be adversely impacted by a grid failure. Life will become very difficult if you and your community can’t provide these life-essential services.

We install many solar power systems in formally “grid-dependent” homes. Solar provides power to the core of the house. Food refrigeration, water pumping, lighting, tool charging, water heating, other necessities and some amenities are all powered by solar. NOTE: Solar can’t heat your home, but there are other renewable energy sources that can. All involve burning something.

The smallest of these off-grid systems charge batteries for radios, flash-lights, security lights, and other small appliances. A moderately sized system can make your home very comfortable and livable during an extended power outage.

At your option, an off-grid system can feed excess power to the grid and “pay down” your investment. However, the term “return-on-investment” does not enter the discussion. What will a life boat be worth when the ship sinks and you are swimming with sharks?

Please consider a visit to the Sunning windpower generator co.,ltd www.sunningwind.com  to see an off-grid self-sufficient system in operation.

Break your dependence on the grid by owning the systems that produce what you need for living. Do you have OPTIONS?

Off grid is the small system, and be independent, you do not need the government support, and generate power to you family use.

Who can help me to find this young clever boy, he make the wind generator by himself

William Kamkwamba dreamed of powering his village with the only resource that was freely available to him.

His native Malawi had gone through one of its worst droughts seven years ago, killing thousands. His family and others were surviving on one meal a day. The red soil in his Masitala hometown was parched, leaving his father, a farmer, without any income.

We are the manufacture of small wind turbine , we really want to help this young boy to solve the erergy problem. But we can not find him.

Sunning is the professional manufacture of wind generator, we could supply you the wind solar hybrid system to generate power and save at the battery bank, also, when the appliances need the energy, it could automatically work.

More detail of our wind turbine system, please click in www.sunningwind.com

But amid all the shortages, one thing was still abundant.


"I wanted to do something to help and change things," he said. "Then I said to myself, 'If they can make electricity out of wind, I can try, too.'"

Kamkwamba was kicked out of school when he couldn't pay $80 in school fees, and he spent his days at the library, where a book with photographs of windmills caught his eye.

"I thought, this thing exists in this book, it means someone else managed to build this machine," he said.

Armed with the book, the then-14-year-old taught himself to build windmills. He scoured through junkyards for items, including bicycle parts, plastic pipes, tractor fans and car batteries. For the tower, he collected wood from blue-gum trees.

"Everyone laughed at me when I told them I was building a windmill. They thought I was crazy," he said. "Then I started telling them I was just playing with the parts. That sounded more normal."

That was 2002. Now, he has five windmills, the tallest at 37 feet. He built one at an area school that he used to teach classes on windmill-building.

The windmills generate electricity and pump water in his hometown, north of the capital, Lilongwe. Neighbors regularly trek across the dusty footpaths to his house to charge their cellphones. Others stop by to listen to Malawian reggae music blaring from a radio.

When he started building the first windmill in 2002, word that he was "crazy" spread all over his village. Some people said he was bewitched -- a common description for people with perplexing behavior in some African cultures.

"All of us, even my mother, thought that he had gone mad," said his sister Doris Kamkwamba.

Villagers would surround him to snicker and point, Kamkwamba said. Ignoring them, he would quietly bolt pieces using a screwdriver made of a heated nail attached to a corncob. The heat -- from both the crowd and the melted, flattened pipes he used as blades -- did not deter him.

Three months later, his first windmill churned to life as relief swept over him. As the blades whirled, a bulb attached to the windmill flickered on.

"I wanted to finish it just to prove them wrong," he said. "I knew people would then stop thinking I was crazy."

Kamkwamba, now 22, is a student at the African Leadership Academy, an elite South African school for young leaders. Donors pay for his education.

His story has turned him into a globetrotter. Former U.S. Vice President Al Gore, an avid advocate of green living, has applauded his work. Kamkwamba is invited to events worldwide to share his experience with entrepreneurs. During a recent trip to Palm Springs, California, he saw a real windmill for the first time -- lofty and majestic -- a far cry from the wobbly, wooden structures that spin in his backyard.

Former Associated Press correspondent Bryan Mealer, who covered Africa, wrote a book, "The Boy Who Harnessed the Wind," after hearing Kamkwamba's story. The book was released in the United States last week.

Mealer, a native of San Antonio, Texas, said he lived with Kamkwamba in his village for months to write the book. The story was a refreshing change after years of covering bloody conflicts in the region, Mealer said.

Kamkwamba is part of a generation of Africans who are not waiting for their governments or aid groups to come to their rescue, according to the author.

"They are seizing opportunities and technology, and finding solutions to their own problems," Mealer said. "One of the keys of his success is ... he's never wanted to rest on his laurels."

Serious forest fire in Canada, seems that the forest fire detection very important

A raging forest fire in the Canadian province of Alberta forced the evacuation of 88,000 residents this week.

Canadian Prime Minister Justin Trudeau calls the damage “absolutely devastating.”

Fort McMurray is in the northern part of Alberta, which is a province in western Canada.

The area around Fort McMurray is known for its tar sands from which oil can be taken. It is the third-largest oil reserve in the world behind Saudi Arabia and Venezuela.

The fire started Sunday and is moving rapidly around the city.


Some people are evacuating south towards the large city of Edmonton. Others are going north toward the work camps close to the oil sands.

Residents report 15-foot-high walls of flame. The skies are gray with smoke and soot.

The Associated Press news agency reports that the fire is especially hard to control because Fort McMurray is warmer and drier than usual for this time of year.

About 1,600 homes and other structures have been destroyed or damaged. Hospitals have been closed and evacuated.

The Alberta Emergency Management Agency says the downtown area of the city is safe, so far.


The evacuation has not been easy. Some cars ran out of gas on the road. Some gas stations were damaged by the fire.

Gasoline trucks were called in to help some motorists refuel on the side of the road.

Many of the oil producers that remove oil from the sands say they will slow production during the fire. Some staff have been evacuated.

Canadian firefighters are looking to cooler weather to help with their battle against the country's most destructive wildfire in recent memory, as officials sought to gauge the damage to oil sands boomtown Fort McMurray.

Cooler weather and light rain stopped the blaze from growing on Sunday, while a change in wind direction took the flames away from Fort McMurray whose entire population has been evacuated, according to officials.

What a serious wildfire in Canada, we really hope that fire will stop and all the citizen could go back home soon, fighting Canada.

As the wildefire is spread quickly, it seems the forest fire cctv system is necessary.Why? Because with the forest fire detection system , when the fire is just begin, it could get the information in the control center, and notify the relevant departments, and take action to put out the fire. Maybe it will not cause the serious loss.
Maybe you will worried about the forest fire camera to the the power to make it 24 hours work continuouly, but Sunning company will help you. We are the professional wind solar hybrid camera power supply system designer and supplier, we will according to the camera power and give you the system suggestion.

The wind and solar energy is the clean and alternative energy, you could get it from environment free. Just need the wind turbine and solar panel.

Normally, we will design it with the wind turbine, solar panel,controller, battery. When the wind is blowing, the wind generator will generate power and storage at the battery bank , and also the solar panel, when the sun rise, it could generate the energy too.


Hope all will be the best soon. Best wishes to you Canada.
