"The company is seeking to add up to 50 megawatts (MW) of geothermal energy from geothermal resource developers at prices not tied to the cost of oil to help lower electricity costs for customers. The added power must also blend operationally with other resources, including renewable energy from wind, solar, biomass and hydro. "Moving forward on geothermal is important to Hawaii Island because we want to increase our use of renewable energy and bring down costs to our customers,"

In 2006, US dry-grind ethanol plants produced 4.9B gallons of ethanol, 72% of overall US ethanol production. Correspondingly, 14.6 mmt of DDGS were produced. USDA FAS records suggest 9% of this was exported. Within the domestic market, 45% of this product was utilized by dairy cattle, 37% by beef cattle, 13% by swine, and 5% by poultry (Markham, 2005). The production of 15B gallons of ethanol from corn grain would result in 37 mmt of DDGS and 50 mmt at 20B gallons.4

An estimate is given by researcher Eleanor Denny. Denny estimates that in order for a facility to be profitable, its capital cost should be less than €530,000 (~$700,000 USD) per MegaWatt which with the current technology is not a realistic goal, meaning that so far the industry produces negative net benefits.50

Brief History of Tidal Power The energy stored in tides been known to people for many centuries. The earliest records of tidal mills are dated back to the 8th Century CE.7 The tidal mills were mainly used for grain grinding and were of similar design to the conventional water mills with the exception of the addition of a dam and reservoir. The industrial revolution increased demand for power but tidal energy never got off the ground, undercut by cheap fossil fuels and other developments which offered easier access to power generation. Existing tidal mills became as obsolescent as pre-industrial water-mills. The first large scale modern tidal electric plant started to operate in La Rance Estuary, St. Malo, France in the 1960s and has been operating ever since. In recent years the search for renewable, non-polluting energy sources and the increase in fossil fuel prices has encouraged renewed interest in tidal power.

The big problem is that there are not many places where you can build a geothermal power station. You need hot rocks of a suitable type, at a depth where we can drill down to them. The type of rock above is also important, it must be of a type that we can easily drill through. Sometimes a geothermal site may "run out of steam", perhaps for decades. Hazardous gases and minerals may come up from underground, and can be difficult to safely dispose of.

Tidal hydropower energy has various advantages. The first of these is reliability and consistency. Other alternative energy sources like wind and solar can have varying amounts of energy generated depending on the weather conditions. Tidal power energy can generate electricity by the clock and indefinitely. This means that shortages can be easily avoided. In addition, tidal turbines are efficient when it comes to generating energy. They can convert about 80 percent of the energy into electricity. Wind and solar energy generators convert much less. Of course, another great benefit of tidal power renewable energy is that it is environmentally friendly. There are no CO2 emissions that are damaging to the atmosphere or Sulfur Dioxide emissions responsible for acid rain.

It’s like buying vs. renting a home. Over the next 10 years a typical homeowner or small business will pay $18,000 to over $50,000 in electric bills, at rates that often increase faster than inflation. When you choose a Bergey wind system you take the same monthly expense and invest it in a tangible asset. Once your Bergey turbine is paid off, you will enjoy more money in your pocket every month for the next 20 – 40 years. Tax credits and rebates make it affordable. Small wind turbines qualify for a 30% federal tax credit and, for businesses, accelerated depreciation.  USDA grants are available for farmers, ranchers, and rural businesses.  Many states offer additional incentives (see www.dsireusa.org).  These incentives make owning a Bergey wind turbine surprisingly affordable.

Geothermal electricity generation does involve a small amount of geothermal pollution in that the steam coming up from below ground carries some toxic gases, but in most plants these gases, as well as the steam, are condensed and reinjected into the ground so the effect on the environment is negligible. There are no CO2 emissions from geothermal energy so it is a much better source of electricity than coal or natural gas or nuclear (or even large-scale hydro generation which requires the flooding of large areas of land).
