These are all important steps, but Mongolia needs to do
more to increase its

By contrast, a transition from fossil fuels to
solar or wind
power, biomass, or hydroelectricity would require rematerialization — the
use of more natural resources — since sunlight, wind, organic matter, and water are all far less energy dense than oil and gas.
As variable renewable
power such as wind and
solar play a larger role on the grid, the ability to time - shift
power consumption will become
more important — not just for customers to keep their bills low in the face
of time -
of -
use rates, but also to match the load to the supply
of carbon - free electricity.
This means
more use of batteries, pumped hydro -
power,
solar - thermal with storage, possibly things like
using excess electricity to convert water into hydrogen and oxygen and storing that until it is needed.
When it comes to California's time -
of -
use rates and the effect they'll have on

The study found support for city subsidies to help make existing buildings
more environmentally friendly; a $ 2.50 surcharge on the average household monthly electricity bill to support public education on energy
use; and support for the installation
of solar panels on city - owned buildings, even if the electricity generated is significantly
more expensive than what what the government now pays for electrical
power.
At the conference they showcased their efforts, including
more than a dozen community
solar projects, the widespread deployment
of «smart meters» that give customers real - time information about their electricity
use, and a range
of microgrids — small, self -
powering energy systems that can disconnect from the larger grid in times
of emergency.
Instead, we get non-dispatchable
power from windmills and
solar PV, both
of which need big subsidies, and electric cars which cost
more, have a high environmental impact and don't meet most people's
use cases, biofuels causing food prices rises, and a lot
of hand - waving about reduction in demand and insulation.
What this means is that in periods (usually during the middle
of the day) when your
solar system is producing
more power than your home is
using, you are credited for the excess
solar energy you feed back into the grid at the full retail rate
of power.
