(CNN) -- Over the next three months Earth's Frontiers will report from around the world on cutting-edge energy technology and fuel the debate on the future of energy.

While more of the world's energy will have to come from renewable sources, clean energy is still more expensive to generate than traditional forms. The challenge is to make renewable energy available at a competitive price and on a scale that meets the world's ever-growing demands.

In the first of our series of programs, Earth's Frontiers will examine the potential of renewable energy.

We'll travel to Hawaii to look at the "Power Buoys" that could soon be used to harness the power of the ocean, and head to Oregon, where fishermen fear the introduction of "Power Buoys" could threaten their livelihoods.

Show times

When it comes to solar power we'll ask, "Is bigger always better?" In Spain we'll investigate the world's largest solar "power tower," which uses hundreds of heliostat mirrors to provide concentrated solar power. And in Britain we'll explore the idea that we can all generate our own electricity using solar panels on the roofs of our homes.

From Denmark, we'll report on the world's biggest off-shore wind farm and marvel at the tiny island of Samso, which meets almost all its energy needs using renewable resources.

But the future isn't just about renewables, and in March, Earth's Frontiers will look at the way more conventional energy sources are shaping up to meet tomorrow's challenges.

The programs will culminate in a studio debate in April, where leading experts will discuss some of the burning issues on the future of energy, and Earth's Frontiers wants your views to be at the heart of the debate.

Should we be going green or sticking with what we've got? Is it time to re-consider nuclear power? Which type of energy has the most potential to meet the world's needs?
