Have you ever researched how much this "FREE" natural resources costs to actually make, replace and dispose of the items needed to capture this FREE resource?
So many people just think sun, wind, wave energy is free, and it is, but the cost to mine, transport, manufacture, instal, dispose of when depleted of the items is much higher than most people think.
It's like turning on your light switch at home, viola instant power. I worked in the control room of a power station for 10 years and, again, people don't know what's involved in producing this instant power.
