Are the big oil companies really spending enough on developing alternative energy?

Go to BP's alternative energy website and you'll notice that they plan on spending 8 billion dollars over the next 10 years on alternative energy R&D. This includes solar, wind, hydrogen and natural gas.

This includes solar, wind, hydrogen and natural gas. Given the fact that we're in a state of complete disarray with the oil situation in our world with many factors contributing to refinery shortages, crude production, etc., you would think that big-oil would be spending a few more dollars on the alternatives. With that said, is BP, et al just giving us all lip service or are they serious about finding a better way. I know that they want their profits to keep rolling in based upon their current business model, but there will come a time when the old way of doing business costs too much (exploration, hurricanes, wars, etc).
Your thoughts on how we can help push them into embracing these technologies and making them viable alternatives for real world applications.
