Why thinking about Solar Off-Grid?
Megatrends in the global energy transition
1. The beginning of the end of the fossil era is here.
2. Renewables are being built faster than coal, gas, and nuclear together.
3. The cost of renewable energy is falling.
4. The energy future consists of a large number of distributed generators,
not a small number of central-station plants.
5. The energy future is digital.
