Energy efficiency
Have you explored your electricity bill? Have you noticed how
many TONNES of pollution your household generates each month?
The main reason for such a horrific pollution figure is a very
low efficiency of electricity generation from fossil fuels, typically
around 20%.
It means that electricity made from fossil fuels is a very "dirty"
kind of energy. For every kWh of such energy that you use, FOUR
escapes via various chimneys to the atmosphere.
Not only that. Exhaust gasses (CO2) from those chimneys form a
trap for Solar heat, contributing to global climate change and
planetary interior overheating that sooner or later WILL affect
us all more than we think.
From the above it is important that energy that we use comes from
sustainable and non-polluting sources (such as Sun and Earth for
example). Even if we waste some of such energy - we create zero
footprint on the environment.
Another side to energy efficiency is a necessity of reducing our
demand for energy, especially from non-sustainable (dirty and
polluting) sources.

It is
very important to be able to understand and quantify
our energy needs. Only then we can see where we really need energy,
where we waste it and how we can reduce our energy needs in the
most effective way.
We are used to measuring "efficiency" by the amount
of money any given gadget costs us to run. While more efficient
gadget will consume less energy and will cost less to operate,
thinking in terms of money is a real barrier for improving energy
efficiency.
Typically, we settle for what we can afford, and if we can afford
it - we don't care about improving anything. We assume that energy
supply is unlimited and the only limit is what we can afford.
Aiming for monetary efficiency (or profit) and energy efficiency
are totally different directions leading to totally different
outcomes. Do you realize that money oriented decisions have brough
us to the situation we are today, where the environment is destroyed
faster than it can recover?
We consider energy efficiency in a wider context - sustaining
The Planet and the Environment. From this point of view it actually
does matter where the energy we are using comes FROM and how much
pollution is generated as a result of its generation and waste.
