We can easily live without coal. We can't live withough the ecosystems that sustain life.

That you would immediately sacrifice friends, family, and even yourself for the sake of the environment? If not, why would you make such a statement towards another individual? Yes, the environment and its state is important because it is a commonality that we share and will share with the generations to come, but to imply that it is more important than an individual and/or group of people is a very mislead thought.

He sees ethanol production as "relatively energy intensive." Pimentel is just a pessimistic about wood waste and switch grass, neither of which he contends are positive energy producers when compared to oil and gas. The term “Renewable Energy” is commonly used these days and everybody seems to have a pretty good idea what it means or stands for. Instant associations of this term include solar power, wind power, hydroelectricity and perhaps biomass and biofuels. Renewable Energy is heralded as the saviour of our planet for a power hungry civilization who is currently burning fossil fuels to meet an ever increasing power demand. But is it true that we could go about business as usual, continue on the same road of ever increasing energy demand, if only we switched to 100% Renewable Energy? To answer this question, let’s go back to the basics of physics: consider, energy cannot be produced, generated, recycled or renewed. It can only be converted (from one state into another). However, every time we perform a conversion, it comes at a cost called entropy, which is a loss of useful or available energy. In thermodynamics, energy is made up of two components: entropy and enthalpy. Entropy is diffuse heat energy, many times associated with waste heat from mechanical or chemical processes and represents - to the largest extent – the useless component of energy that is unavailable to carry out work. Entropy is also associated with the level of disorder in a system. Enthalpy on the other side is the useful (non-diffuse) energy component that we can readily use to carry out work. Thermodynamics teach us that every time we use enthalpic energy (eg change it from a state of stored chemical energy into mechanical work) the total entropy of the system in which it occurs (our planet) increases. The larger the energy potentia, the larger is the amount of useful work we get from it. And here we are at the core of the problem: the entropy of a system (heat and disorder) increases over time as enthalpic energy is spent. This process is irreversible and forever reduces the usability of useful energy that remains. For this reason, fundamentally and despite popular believe, there is no such thing as “Renewable Energy”. Out of all sustainable energy initiatives available, the drastic reduction of our energy demand, also know as “demand side abatement” is the single most important one. If we continue to increase our energy consumption, even if we use “renewable” sources exclusively, we will necessarily also continue to increase the entropy, waste heat and resulting temperature in our planet’s atmosphere. Before we started burning fossil fuels, our planet was in good balance between the sun’s radiation absorbed and the heat earth re-radiated into space. This balance depends on many factors, including the gas composition of the atmosphere and cloud cover, however their individual roles and interdependencies in context with radiation absorbed and re-radiated are complex and still poorly understood. As we are running out of time to fix the problems associated with climate change, we cannot afford to take new chances and make assumptions about the safe and abundant use of “renewable” energies. Instead, we should take the more conservative view that we live on a planet with limited, finite resources, the use of which produces an ever increasing entropy. Since this process is irreversible, the best strategy for us is to reduce our energy consumption and thereby extend our lease.

This energy that supports countless businesses, keeps your lights on, and prohibits you from freezing to death in the winter doesn't come from the wind, Obama's stimulus package, or even the Sun, as much as people hate to admit it, it comes from coal! The fact of the matter is that coal has kept this country afloat and provided it with energy for the past hundred years, and has the potential to keep doing so for at least 50 more, given the chance, and right opportunities. The sudden uproar from all the "tree huggers" as I like to call them, to make everything as "green" as possible is happening way to fast, and the sudden hatred of coal will cause this great nation to pummel into even more of a crises than it is already being faced with. What people don't realize is that the coal industry is one of Kentucky's top employers and is the only thing that many people know, they grew up around coal, and it is apart of their everyday lives, much as it is mine. My Dad has worked in the coal mines for every bit of 25 years, just to try and give his family a better life, and better opportunities to succeed in the future. My point is if you take away coal without another energy source that has been proven to be as affective, which none has, then your going to take away life as many of us know it today, not to mention jobs, homes, and families torn apart.
