The problem is, that wind doesn't replace generating capacity, it's in addition to. You must have baseload, mostly through natural gas, to match that wind production. it's a good way to reduce CO2 as it can be used as a low emission source when the wind blows, but in the end it does increase our capital costs because you techncially haven't added any reliable generation. Same with solar. Basically these renewables mean paying for generating capacity twice. Once for when they are useful, and again when they are not. If this is the plan, expect energy costs to go way up.
