Solar's fine, but very inconsistent. I work in natural gas myself, but I know quite a few people in Solar. It's great in some areas, not so great in others. They get a lot of calls during the winter wondering why they're getting no production out of their panels when it's snowing or has recently snowed.

Wind more and more is looking like it might be a nightmare. Natural gas is way cheaper in terms of energy provided when you factor in maintenance costs of wind turbines. In addition, there's significant concerns about the environmental impact of wind farms.

Natural Gas is actually insanely good right now in terms of carbon footprint versus cost. Most countries don't have the infrastructure for NatGas E&P though like we do in the US, and it's mostly a local resource.
