We Can Solve the Climate Crisis | Green Business | Reuters: "The report has some academic heavyweights, notably Dan Kammen of Berkeley, behind it, so it is well worth a look. Among other things, it investments required to bring the different technologies to scale. Notice, for example, how building efficiency is a much, much cheaper way to reduce greenhouse gas emissions that solar thermal power or nuclear. Here are some highlights:

• Biofuels can achieve gigaton scale for an investment of $383 billion, and enhance energy security by displacing foreign oil imports.

• Building efficiency can achieve gigaton scale for an investment of $61 billion, creating 681 thousand direct new jobs. It’s the lowest cost pathway of the nine in the report.

• Concentrating solar power (CSP) can achieve gigaton scale for an investment of $2.24 trillion. Because it’s ideally suited to remote desert areas, new transmission lines will be needed to get the electricity to cities.

• Construction materials can achieve gigaton scale for an investment of $445 billion, creating 328 thousand direct new jobs. An example: low-carbon cement.

• Geothermal can achieve gigaton scale but technological advances will be needed. The investment required will be $919 million. (If you missed it, check out thi"
