Change
This section brings together pieces on the various drivers of change.
The costs of the four key renewable energy technologies have been falling on mathematically significant learning curves.
The most likely future is that these costs will continue to fall as set out below. The implication is that by 2050 we will have $10 per MWh solar electricity deployed in $30 per KWh batteries. These costs are far below the costs of fossil fuel technologies, and low enough to solve any lingering concerns about system costs, intermittency and integration.
