The world is facing
an energy and climate crisis. Globally, the energy sector emits 26
billion tonnes of CO2 each year and electricity production alone
accounts for 41% of emissions. The International Energy Agency
expects CO2 emissions in 2030 to have increased by 55% to reach
more than 40 billion tonnes of CO2. The share of emissions coming
from electricity production will increase to 44% in 2030, reaching
18 billion tonnes of CO2. Europe is going to be importing a growing
share of its energy at unpredictable but most likely higher prices,
from unstable regions, in ever-fiercer competition with the rest of
the world and at staggering environmental cost. Spare electricity
generating capacity is at a historic low. Europe has to invest in
new capacity to replace ageing plants and meet future demand. In
the period 2005-2030, the EU needs to install 862 GW of new
electricity generating capacity. 427 GW of generating capacity will
be retired in the EU and an additional 435 GW will be needed to
satisfy the growing demand for power. The required capacity exceeds
the total capacity operating in Europe (723 GW). Satisfying our
energy needs over the coming decades will be a big challenge. For a
region that currently imports 56% of its energy – and is on track
to reach 70% in the next 20 to 30 years – the challenge is big. Our
own...

All right, my friend,
You are concerned about the waste. So, all I can tell you is: What do you suggest we do?
We have two years left before oil and gas cost ten times more
than today; solar energy and wind turbines can supply maximum 7
percent of our total consumption of energy; oceans are littered
with plastic bags, wrappings, and are 80 percent DEAD; the sun is
getting hotter; we are killing the great forests to get wood to
burn (and transform into paper); Earth's temperature is rising 2
degrees Celsius (which is huge) due to CO2 and methane.
What would you say if we could recycle and reutilize nuke waste
and nuke plants?
Think again: We have two years in front of us before the great
depression.
What do you suggest we do?
Friendly,
Fred
