Spudda tells us it’s all done!
A short introduction to a historic report, published 12th April 2019 by LUT University and Energy Watch, that models the global energy system on an hourly basis using the real economics of existing renewable energy technologies. A unique first, and essential ammunition for all worried about climate change.
We’re saved? We can power the world on 100% renewables!
Except, well, page 18 of the main report.
Storage technologies play a vital role in enabling
the transition towards a fully renewable energy
system across all sectors. As shown in Figure 3.1-4,
a significant share of electricity demand is covered
by storage that increases through the transition
period up to nearly 5000 TWhel by 2030 and further
significantly increases to over 30,000 TWhel by
2050. As the shares of solar PV and wind energy
increase significantly beyond 2030, the role of
storage is crucial in providing uninterrupted energy
supply. The ratio of electricity demand covered by
energy storage to electricity generation increases
significantly to around 18% by 2035 and further on
to about 23% by 2050, as shown in Figure 3.1-4.
Electricity storage technologies cover most of the
storage requirements from the electricity sector,
complemented with some shares of electricity
derived from stored heat. This cross-sectoral
storage is enabled through an integrated power
and heat sector
OK, super. So energy storage will become effective and economic.
So, which technologies? Umm, what’s that? They will? You are assuming that are you? Ah, you are.
So, OK, sure we can power the world on renewables if we only had an economic method of electricity storage. But assuming that we do doesn’t prove that we can now, does it?
This also amuses:
A global transition to 100% renewable energy across all sectors – power, heat, transport and
desalination before 2050 is feasible1. Existing renewable energy potential and technologies, including
storage, is capable of generating a secure energy supply at every hour throughout the year. The
sustainable energy system is more efficient and cost effective than the existing system,
Great, so we don’t need to do anything about it, do we? Private lust for profit will get us to this more efficient and economic system on its own.
Good, glad we’ve got that settled.
