i asked sunrun's lynn jurich is the prevalence of solar inevitable and how soon can we reach the pointwe are only at 1% of u.s. households penetrated today, but the growth rate we have been able to achieve in just eight years, nine years of time, from zero to 100,000 customers with adoption at 100% year over year, that starts to compound and it will happen faster. emily: how much faster? lynn: i could imagine that solar is about 20% to 30% plus of our energy sector within three years to five years. emily: what are you doing to reduce installation costs and will solar ever be competitive with utilities without tax incentives, without other incentives and tax credit? lynn: solar is competitive today. a lot of people do not know is that all of energy is subsidized. the global subsidy for fossil fuels are $5 trillion, so fossil fuels in the u.s. receive eight times the subsidies that renewables did in the u.s. what we are saying is let's have an even playing field. so today, even with the subsidies fossil fuels received, we are 20% cheaper and costs are going down. the power is going up at

emily: that was sunrun ceo lynn jurich., we spoke to a company that could become the first in the world to generate a serious amount of energy from our ocean tide. u.k. start up is proposing a multibillion dollar project that would supply power to coastal cities in wales. it is in negotiation with the british government to secure the subsidies for the project to go ahead. the chairman keith clark sat down with caroline hyde and london. she began by asking how his title technology would work. keith: the tide comes in twice a day, goes out twice a day and we built a lagoon, a big pile up encloses the large piece of area and turbines make power predictably. it is dumb technology capable of improvement, it is safe technology and it is going to work and it works for about 120 years. it is the moon, so this is just such an easy way of harnessing islly efficient energy, that low carbon and it is predictable. caroline: talk about the scale. keith: the great things about the lagoons is the bigger you do it, -- so our first one is ab

emily: that was sunrun ceo lynn jurich.ith renewable energy, this week, we got a chance to speak to a company that could become the first in the world to generate a serious amount of energy from our ocean tide. u.k. start up title look to power is- tidal lagoon proposing a multibillion dollar project that would supply power to coastal cities in wales. it is in negotiation with the british government to secure the subsidies for the project to go ahead. the chairman's keith clark sat down with caroline hyde in london. she began by asking how his tidal technology would work. keith: the tide comes in twice a day, goes out twice a day and we built a lagoon, a big pile up rock that encloses the large piece of area. turbines make power predictably. that is the great thing. it is dumb technology, capable of improvement. it is safe technology. it is going to work. it works for about 120 years. and we will tell you when you will get power four times a day, because it is the moon. so this is just such an easy way of harnessing really
