Filmmaker Bill Lishman journeys around the world in search of earth’s renewable energy. He discovers Canada’s rich history of hydroelectric production, finds the world’s largest solar power plant in the Mojave Desert and makes the discovery that 25% of Denmark’s electricity is produced with wind turbines. Lishman explores North America’s wealth of renewable resources and looks at ways other countries are harnessing earth energy in clean, safe methods.

Do you remember the children's tale, "Three Little Pigs?" Build a strong house made out of bricks and mortar, and you'll be safe from the big, bad wolf. Build Green is here to show audiences that a house built from sticks and straw is better protection from the elements, and it mitigates your personal impact on global climate change.

In a refreshing hour, Build Green advises making the sun, wind and rain — along with dirt, straw and sewage — your friends. By building a house using innovative practices and materials, you'll not only do the earth a favour, but you could save big bucks too.

In Build Green, Canada's best architects hype their green creations. From retro-fitting a hip, old Montreal housing complex with state-of-the-art sustainable energy systems, to pitching hay for strawbale houses, to building transportable "mini-homes" with their own small power plant, take a close look at the materials and means we can all adopt for building green homes.

The Suzuki Diaries is a road trip, a travelogue, an adventure. The legendary David Suzuki and his youngest daughter Sarika, a university student about to start her own career in the sciences, are full of hope as they travel to Europe to see what sustainability truly looks like.

In Germany, Denmark, France and Spain, they set out to meet the people working to restore the equilibrium between human needs and planetary limits. They find a renewable energy expert, a biodynamic farmer and writer, a blogging bike enthusiast, two meticulous industrial designers, and a political powerhouse in the green movement. What they discover is that sustainability can be built into the fabric of contemporary life, not just by environmentalists but by anyone, across the full spectrum of society. The idea, innovations and inspiring individuals David and Sarika encounter prove that sustainability does not mean sacrificing quality of life.

The Suzuki Diaries illustrates what is truly possible if humans have the will.

Join engineering professor Brian Fleck on a quest to meet the engineers, designers and even students working on new technologies to make this possible. From hydrogen-powered family sedans to high end fully-electric powered sports cars, and even cars that drive themselves, you'll find plenty of surprises. Perhaps the future is not so far off as we might think — the technology that will transform our societies tomorrow is being developed today. The question is, are we ready?
