earth, the final frontier

Clean Energy, Clean Environment

We are at a cross roads in human history, we can choose to continue on as we have been, or we can make a change to improve our future and quite possibly the future for several generations to come. We are here to promote energy independence, a better environment, a secure future and a higher return on investment for your hard earned dollar. It is what I believe in, it is why I am in the solar business.

Solar future or no future

Our sun, either directly or indirectly, powers almost everything we do.  The only non-sun power used on Earth is nuclear energy, the production of which, as of 2005, amounts to about 6.3% of the total energy used.   The rest of the world’s energy is solar energy, either directly, indirectly by use of hydro or wind power, or through energy stored in fossil fuels such as oil, coal and natural gas.

The process that created these fossil fuels is complex and took several millions of years to complete.  Humans began to uses fossil fuels as primary energy sources during the 1850’s.  Since Then, the use has grown exponentially because the use of coal and oil allowed larger, more powerful machinery to extract and transport more coal and oil. What took nature hundreds of millions of years to create, humans have burned through in about 160 years.

The process for creating fossil fuels begins with photosynthesis.  The sun’s energy provides the engine for plants and other vegetative matter to fix carbon molecules from CO2.  Carbon fixation is the process that generates oxygen (O2) in our atmosphere and is the central process that allows life to exist on earth.

Once carbon is released from CO2, it is bound into long and short chains with sugars and starches that create plant structures.  These plants either die and decompose or are consumed by animals which in turn die and decompose.  The organic material is then broken down into carbon and hydrogen compounds in various forms.

There is no substitute for photosynthesis when it comes to carbon fixation.  In short, plants are the most efficient way to break up CO2 into its base elements creating the building blocks for life.  Basically, we are burning through our energy supply a million times faster than it can ever be replaced.  Surely this system is not sustainable and eventually will run out of fuel.  If the peak oil theory is to be believed, that will happen sooner, rather than later.

As outlined in the post “The Sun Powers Everything,”  even if all of the variables are considered, there is more than enough energy strikes the earth everyday to power all of our current needs and then some.  With the current technology, we can tap that power and make a useful and significant reduction in our fossil fuel use.  As technology evolves and more efficient devices are designed and manufactured, more of that power can be converted directly into heat and electricity for us to use.

Without solar power, humans will run out of energy and the life and society that has taken thousands of years to develope will colapse.  This is the most pressing issue of our time, all else pales by comparison.
