W: There has recently been a steady drumbeat of reports from climate scientists warning that there is less and less time for us to take collective action to slow the disastrous effects of climate change. We’ll be looking at various, innovative energy efforts periodically, starting with one underway in Scotland. Today we have Mr. Scott from Scotland with us to shed light on this issue.
   M: Thank you. Our country is nearly 70% powered by renewable sources already, with the goal of reaching 100% by 2020. The power traditionally came from deep sea oil and gas, but the ocean has a lot more to give.
   W: Some reports say wind turbines are quite popular in your country. So what is new this time?
   M: In a giant industrial hangar on the eastern coast of Scotland, technicians are servicing two turbines, but they’re not wind turbines this time. These are actually designed to be 100 feet underwater, capturing energy not from the wind, but from tidal currents.
   W: Sounds quite innovative. Tell us a bit more about this new technology.
   M: Once we get this 150-ton turbine into the water, this entire thing will swirl with the tide, four times a day, generating enough power for 1,000 homes.
   W: What are the blades made from?
   M: The blades are made from carbon fiber.
   W: Once in the water, how do the turbines work?
   M: As the tide ebbs and flows, the turbines spin between 7 and 15 times a minute, generating power, similar to a wind turbine. Cables carry the energy back to the shore, first underwater, then underground, where it’s then fed into the national grid. The tides are so predictable that Atlantis says it can tell how much energy these turbines will generate every 15 minutes for the next 25 years.
   W: Do we have to worry about the weather condition?
   M: You don’t have to worry about whether there are clouds on a sunny day for solar. You don’t have to worry about whether there’s a stiff breeze or not. That’s the real advantage of tidal energy： it’s very, very predictable.
   W: I heard that Scotland is estimated to have a quarter of all the tidal energy resources in Europe. And Scottish companies have helped lead the way in developing technology to harness those currents.
   M: Yes. MeyGen, here in northern Scotland, is the world’s largest planned tidal project, and over the next four years, SIMEC Atlantis is planning on installing more than 250 additional turbines.
   W: When it’s fully done, more than a quarter of a million homes can benefit from the power that’s generated from this array of turbines, right?
   M: That is correct.
