Replace oil? How can something so monumental be accomplished? Preempt waste, start small, provide better service at lower cost and think better.
Should we choose to have 20% of our power production ideologically clean, or 80% of our electricity needs atmospherically clean? The answer is: we should do both.
Reducing one's energy overhead costs relatively little and produces a revenue stream that appreciates over time. Replacing one's energy infrastructure with on-site renewable systems, in contrast, will require a sizable up-front financial commitment relative to what it will produce over time.
We can change the lifeblood of our economy from oil to ingenuity. It is that way in communications. It was that way with transportation. Open rights of way to innovation. Ingenuity will flourish or fail based on the value created minus the cost to compete.
EIA's monthly and annual predictions have only one purpose: to prevent the mainstream media from alerting the driving public to the fragility of the domestic energy picture.
Oil finding rates -- increasingly difficult and costly-- are now only about 50% of current oil consumption. Does more need to be said for the inevitable "Hydrogen Economy"?
I am no longer worried. Now that I understand there is no energy crisis, no ingenuity crisis, only the need for well-meaning bureaucracies to adapt policies to rapidly changing assumptions, I am terrified.
While all investments pose some degree of risk, the return on a solar energy system is about as safe and predictable as, well, the rising sun. Fortunately for the Earth and its varied inhabitants, the center of our solar system is situated well beyond the reach of humanity's capacity to tamper with a good thing.
I would like to point towards one combination of existing technology that I am convinced could actually do the job of lowering atmospheric carbon concentrations and thus reverse climate change
Using natural gas to produce oil from tar sands is akin to turning gold into lead.
We are being marginalized, patronized and ignored by our current energy policies. We're not being encouraged, or even invited, to participate individually in the solution to the problem. I feel that it's incumbent upon each of us to "plant our own renewable energy ‘Victory Gardens'".
"Tennessee Valley Authority does away with solar subsidy." Would any businessman who knew that his obsolescence was imminent not do likewise?
Few people realize what a huge impact several hundred thousand solar water heaters can have on a country's energy demand. Thermal solar (heating water) is a sensible and efficient way to avoid the expense and potential danger of nuclear plants. Hot water is always needed and solar energy is the best method to meet those demands. Since thermal solar heats our oceans, isn't it about time we utilize the proven technology of solar water heaters?
Of course, the situation for each business is different but considering renewable energy resources as part of a comprehensive disaster plan should also be part of the discussion.
Interdisciplinary cooperation of specialists from engineering, natural sciences, economics and humanities have now become as self-evident for large dam projects, especially those with considerable use of hydro power, as have public relations and awareness raising with the broad population.

Joyce Solar Actuators are designed to precisely position smaller solar tracking equipment. Their robust and efficient DC motor (24V or 36V) keeps power consumption to a minimum. Travel speeds remain nearly constant regardless of the load. Ideal for rugged environments common to the solar industry, these cost-effective SA actuators have an IP65 protection rating. Self-locking features in the mechanism ensure that the solar actuator will hold position throughout the daily tracking cycle. Specifications: â€¢ Double clevis mounting for easy installation â€¢ Clutch for overload protection â€¢ Adjustable limit switches for flexible travel settings â€¢ Reed sensor digital feedback for accurate positioning â€¢ Duty cycle is 25% (4 min. running, 12 min. rest) â€¢ Lubricated for life
