Hugh,

It is unfortunate that I do not have an understanding of basic
physics, nevertheless, you had answered the issue with your reply.
That we, humans had distorted the natural environment of the earth
and this is done through energy wastage resulting in an incomplete
natural transformation of the available energy on earth.

It is not the amount of energy resources that is available but the
conversion of energy that creates an inbalance environment that
matters. Energy can be used naturally by the environment or
unnaturally by human.

In simple term, if we are replacing fossil fuels with solar energy,
it is estimated that 432.5EJ (energy used from fossil fuels in 2005:
from
http://en.wikipedia.org/wiki/World_energy_resources_and_consumption)
is absorbed from the sun's ray on earth, which originally is
absorbed by the environment.

With increasing energy usage by humans, more energy will be "taken
out" from the environment causing an inbalance situation and a
likely "climate change"
This is similar in concept with the displacement of fossil fuels
from under the ground into the earth's atmosphere.

To avoid these situation, we should avoid excessive and wasteful
usage of these resources be it fossil fuels, solar or any other
alternaives.
