Off shore works well but the central area of North America works fine. Unfortunately New York, Toronto, Montreal were all established in relatively wind free areas many years ago so they need a power grid to get the energy to them. Wind also has the advantage of being available when all those office lights in the buildings were on in the video.</div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">There are a couple of problems with solar, first the cost of connecting to the grid is quite high. More than 50% of a home roof top installation costs are for permits and connections. That's why OREC.ca likes bigger roofs and ground solar arrays. The second problem is roof vents, they limit where solar panels can be placed on the roof. Currently there are very few roof vents in OSM to see where solar panels could be placed. Very few buildings have enough roof detail to see if the slope is in the right direction for solar panels.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">OREC accept that wind turbines are nice but the most efficient ones today are big and that means expensive $3-4 million dollars each which they think they can't affordon a local coop basis. A wind farm makes sense from a logistics point of view but a decent wind farm has many turbines, we aren't talking local here. The bigger they are the more efficient they are and the more likely to produce a steady stream of electricity.<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"> Most are around 499 feet tall, the FAA require extra steps in their approval process if its higher than 499 feet.
