In plain language, master electrician and solar installer Bruce Hankins explains AC coupling, the combining of a grid-tied solar electric installation with an off-grid battery backup system.

As the world turns to sustainability, solar enriches our lives. SAVING SUNSHINE takes a look at today's developments in solar electricity and its increasing role as power provider.

Combining the best features of off-grid, stand-alone solar installations with grid-tied systems that provide distributed generation, photovoltaic systems have evolved into AC-coupled systems. They provide back-up, stand-alone electricity while also using renewable solar energy for our everyday electrical needs.

This combination of renewable energy and energy storage connects multiple inverters with maintenance-free batteries and opens the door to energy independence in a sustainable, low-carbon future.

Teachers, electricians, system installers, architects, owners of grid-tied systems and solar advocates will find the clear explanations in SAVING SUNSHINE helpful in learning the specifics of an AC-coupled system and how it forms a local distribution system to deliver electricity in a more reliable and environmentally friendly manner.

The energy demands and rising cost of oil have encouraged scientists and engineers to develop renewable energy alternatives. Biofuels are renewable energy sources from organic materials such as plants or animals that are directly converted into liquid fuels. The two most common biofuels in use today are ethanol and biodiesel. Engineered biofuels, such as ethanol and biodiesel that are made from starches, sugars and cellulose are already in use as blending agents and additives that greatly reduce vehicle emissions. Algae as a bio-fuel has become more common because it is easy to harvest and these single celled photosynthetic organisms are known for their rapid growth and high energy content.

Reveals the true social and environmental costs of coal power and looks at promising developments in renewable energy technology.

In the digital age, half of our electricity still comes from coal. DIRTY BUSINESS reveals the true social and environmental costs of coal power and tells the stories of innovators who are pointing the way to a renewable energy future.

Guided by Rolling Stone reporter Jeff Goodell, the film examines what it means to remain dependent on a 19th century technology that is the largest single source of greenhouse gases.

Can coal really be made clean? Can renewables be produced on a scale large enough to replace coal? The film seeks answers in a series of stories shot in China, Saskatchewan, Kansas, West Virginia, Nevada and New York.

The film features amongst others: Robert Kennedy Jr., Bill McKibben, Dr. James Hansen, Myron Ebell, Don Blankenship, Joe Lovett, Maria Gunnoe, Dr. Vaclav Smil and Dr. Julio Friedmann.

  • "A must-see for anybody concerned with our environment and energy future." - Brent Yarnal, Department of Geography, Penn State University

  • "The best and most comprehensive look at global dependence on coal, and explores some promising alternatives...wind, solar thermal, increased energy efficiency through recycling 'waste heat'--which makes this a valuable resource for science as well as social studies classes...Dirty Business is a fine and lively overview of a complicated issue." - Rethinking Schools

    Wind power... it's sustainable ... it burns no fossil fuels...it produces no air pollution. What's more, it cuts down dependency on foreign oil.

    That's what the people of Meredith, NY first thought when a wind developer looked to supplement the rural farm town's failing economy with a farm of their own -- that of 40 industrial wind turbines. But when a group of townspeople discover the impacts that a 400-foot high windmill could bring to their community, Meredith's residents become deeply divided as they fight over the future of their community. With wind development in the United States growing annually at 39 percent, Windfall is an eye-opener for anyone concerned about the environment and the future of renewable energy.

    An inspirational portrait of a young West African man who starts a business building solar panels from scratch and selling them to rural customers in Mali.

    6-year-old Daniel Dembele is equal parts West African and European, and looking to make his mark on the world. Seizing the moment at a crossroads in his life, Daniel decides to return to his homeland in Mali and start a local business building solar panels -- the first of its kind in the sun-drenched nation. Daniel's goal is to electrify the households of rural communities, 99% of which live without power.

    BURNING IN THE SUN tells the story of Daniel's journey growing the budding idea into a viable company, and of the business' impact on Daniel's first customers in the tiny village of Banko. Addressing climate change, poverty, and self-sufficiency, the film demonstrates how a small-scale, local business model can provide jobs, appropriate technology, and empowerment to people everywhere. The film also explores what it means to grow up as a man, and a vision of what it takes to prosper as a nation.

    Simply put, geothermal energy derived from heat produced by the core of the earth. Geothermal energy is one of the oldest renewable resources used by humans. It has been used since the Ancient Roman times as a heat source. Recently, we have begun to harness that energy as a source of power. Geothermal power plants take the heat from the earth and bring it to the surface to create steam that spins a turbine. We have a constant supply of heat from the earth. The challenge is finding where it is strongest and bringing it to the surface. The Eco Kids will guide us through this process and explain a few different ways that geothermal power plants operate. Find out how experts are working to fine tune the process and make geothermal power plants more affordable and useful across the country.

    How can America truly end its dependence on fossil fuels and transition to green power?

    Power Paths is an inspiring documentary about how Native American communities across the West are leading the transition to alternative energy sources.

    Ten percent of America's energy comes from Native American lands, including a third of the U.S. coal deposits and hydroelectric dams that feed the grid. These coal mines and plants brought jobs to the region, but they also brought pollution, cancer and environmental destruction.

    Power Paths chronicles the efforts of several tribes as they fight to end the harmful use of coal and work to bring clean, renewable energy projects into their communities, including wind and solar power. As Power Paths reveals, many Native American tribes are not waiting for the government to act. Instead, they are actively seeking investors and a way to control their own energy and sell the rest to the power companies.

    As the nation at large struggles to disengage itself from the chains of a fossil-fuel-based economy, Power Paths signals cause for hope that an alternative is not somewhere in the future, but possible right now.

  • "Power Paths is a powerful and revealing documentary that addresses balance between conservation and preservation at a level that affects Native Americans... but has larger reaching implications on us all. It is a must see." - Ed Foreman, Programming Director, Trail Dance Film Festival

    Brazil claims to have stolen a march on the industrial world. It's developed a cost-effective alternative to petroleum by growing sugar to produce ethanol.

    Brazil's sugar crops are a great source of the petrol-substitute ethanol. And now rising oil prices and Brazil's production of ethanol have led to an automotive revolution in the country.

    Car manufacturers in Brazil have created the flex car -- a vehicle that can run on either ethanol or petrol, or any combination of the two. Over 1.3 million flex cars are now running in Brazil - more than half total car sales

    The foundations for the country's "sweet revolution" were laid during the oil crisis in the 1970s, when Brazil's military-led government bankrolled the development of the ethanol industry.

    Ethanol can be produced from many crops but, in Brazil, it is made from the most potent and cost effective crop of them all, sugar cane. Brazil is the world's largest exporter of sugar and the biggest producer of ethanol.

    Sugar has been grown in Brazil for centuries, it's the conversion to alcohol that's a relatively new phenomenon.

    In north-east Brazil, much of the harvesting continues to be done by hand. Each man works a 10 hour day, 6 days a week, and cuts 8.5 tons of cane.

    The Brazilian government sees ethanol as a chance for the country to boost its economy by becoming a major exporter.

    Car manufacturers claim that the change to cars running on ethanol can be achieved without great costs. Special software helps the car to adjust for whatever mix of petrol or ethanol it's using.

    But it's not just on the roads that ethanol is powering Brazil. The world's first ethanol-fuelled planes are now being built.

    In Brazil, the price of fuel has helped convert millions to ethanol. But they're also claiming environmental advantages because ethanol exhaust gasses are cleaner.

    But not everyone is convinced that ethanol is Brazil's environmental saviour. Burning off sugar cane before the harvest is widely considered to be bad environmental practice.

    And although ethanol may be a renewable fuel, growing more sugar puts pressure on home soil. The sugar industry has a bad track record when it comes to looking after the environment, and forests throughout Brazil are being destroyed by the sugar farmers.

    Germany is leading the world in encouraging renewable energy. By 2050, half of its energy could come from renewable sources. But what's the real cost of its energy revolution?

    Germany's landmark EEG law compels power companies to buy electricity at above market prices, from anyone using renewable technology to generate it. "It's the beginning of an energy revolution," says politician Herman Scheer.

    The renewable revolution has already come to the German village of Juhnde where residents now produce their own electricity from manure.

    "I'm personally very happy," says one resident, "because now I am independent of the international oil prices." 30 neighbouring villages are so impressed they're planning to invest in their own plants.

    Germany is now the world leader in renewable energy. 10% of its electricity requirements are now supplied by wind, solar, bio-mass and small hydro. That will grow to 20-25% within 15 years, when nuclear is scheduled to be phased out.

    The EEG law has also led to a boom in solar power. Near the German city of Leipzig is a brand-spanking-new solar panel factory using groundbreaking technology developed in Australia. Germany's support for renewable energy is sucking in technology from around the world.

    Germany's renewable energy industry now employs 170,000 people - a new industry. But not everyone is a fan. Power companies, forced to buy renewable energy at a high price, pass the cost onto consumers and business.

    This means electricity for domestic use is the most expensive in Europe - for business it's the second most expensive. The critics say that makes some parts of German industry uncompetitive - and actually costs the country jobs.

    For Germany's big four energy companies, renewables represent a big threat. With conventional power stations, they make money both from power generation and from distribution. But with renewables they are largely restricted to distribution alone.

    Dieter Schaarshmidt is a renewable energy pioneer. He manages a windmill co-operative and is aiming towards 100% renewable energy in the region. "We think that renewable energy should be owned by the people in the region," says Dieter. But the bigger companies are already starting to take over.

    The big power companies argue that renewables can't guarantee supply. And because electricity itself cannot be stored on a large scale, they say for the foreseeable future, renewables can only fill a minor, top-up role. And they're getting support from some German politicians who want to keep open the option to use nuclear power.

    But Hermann Scheer says renewables alone can meet Germany's entire energy needs, because hydro and bio-mass can guarantee supply when wind or solar are not available. He says the power companies oppose renewables for financial, not technical reasons.

    "The most important question is how long do we need?" says Scheer, "Because if this development is postponed and postponed again and again, then we will lose the race against time."

    Renewable energy offers a long term solution to the problems caused by our use of fossil fuels, but if we want to make an immediate impact, the best place to start is energy conservation. Developed countries like Australia have relied on cheap energy to maintain high living standards, but this has produced a culture of wastefulness and inefficiency. This program takes the audience on a tour of an energy efficient house to show how the average home can cut energy use. And to make sure the audience identifies with the subject, we also visit an average Australian household and an average Australian secondary school, to see what they've done to conserve energy. Once people are educated about the way we use energy, they realise how easy it is to make the small changes that are needed to cut our energy use. This program shows that this results in big savings on our energy bills and makes a significant contribution to the health of our planet.

    A fitting description of the continually self-regenerating energy and raw materials resource generally known as biomass might well be solidified solar energy. As a key link in the carbon cycle, tremendous amounts of vegetable material with concentrated reservoirs of energy locked inside are being manufactured round the clock by that greatest of dynamos, the sun. The sheer quantities of material are as enormous as the potential uses for biomass are diverse. Examples taken from various European countries show how effectively energy can be extracted from vegetable materials using a wide variety of methods all determined by specific regional and economic conditions, and yet all highly efficient and all friendly to the environment. The self-regenerating resource called biomass is an ideal example of the harmonization of economy and ecology.

    The voracious appetite of the worlds six billion people for energy has given rise to a fast-food system of power supply and consumption. But there is only one source which can truly satisfy this hunger forever: the sun. Like many other visions of the future, the long-touted revolution of solar energy failed to materialize by the end of the millennium. But in the tradition of Prometheus, the pioneers are thinking ahead and, at the same time, blazing a trail for the world to follow, from the photo-voltaic roofers of Austria, to the cottage energy industry of Switzerland, to the architects of a solar village in Sweden; from the grass-roots solar revolutionaries of Germany to the energy entrepreneur with the competitive edge in the U.S.A. the spectrum runs from visionaries to pragmatists who have all put their faith in the only inexhaustible resource. But its only the beginning of a long, long road from shortsighted, fast-food energy consumption to a solar world energy order. The means and the end are a new technology of light.
