"Ever since ancient Romans installed glass and mica around their southern-facing door entrances, people have been finding ways to harness the power of the sun. From those origins, solar energy has slowly progressed into a viable source for powering your home. Other People Are Reading"

"Primary sources of noise associated with exploration include earth-moving equipment (related to road, well pad, and sump pit construction), vehicle traffic, seismic surveys, blasting, and drill rigoperations. Well drilling and testing activities are estimated to produce noise levels ranging from about 80 to 115 decibels at the site boundary. Air Quality Emissions generated during the exploration and drilling phase include exhaust from vehicular traffic and drill rigs, fugitive dust from traffic on paved and unpaved roads, and the release of geothermal fluid vapors (especially hydrogen sulfide, carbon dioxide, mercury, arsenic, and boron, if present in the reservoir). Initial exploration activities such as surveying and sampling would have minimal air quality impacts. Activities such as site clearing and grading, road construction, well pad development, sump pit construction, and the drilling of production and injection wells would have more intense exhaust-related emissions over a period of 1 to 5 years. Impacts would depend upon the amount, duration, location, and characteristics of the emissions and the meteorological conditions (e.g., wind speed and direction, precipitation, and relative humidity). Emissions during this phase would not have a measurable impact on climate change. State and local regulators may require permits and air monitoring programs. Cultural Resources Cultural resources could be impacted if additional roads or routes are developed across or within the historic landscape of a cultural resource. Additional roads could lead to increased surface and subsurface disturbance that could increase illegal collection and vandalism. The magnitude and extent of impacts would depend on the current state of the resources and their eligibility for the National Register of Historic Places. Drilling activities could result in long-term impacts on archeological artifacts and historic buildings or structures, if present. Surveys conducted during this phase

"Fossil fuel power stations typically cost about $2.1 dollars per watt to build solar stations around $7 at present. The efficiency is increasing and costs are falling. This of course does not represent the cost to the consumer. In addition it does not take into account all the various other costs and the advantages and disadvantages of each. Fuel (fossil stations), poor sunlight (solar stations). Maintenance costs are similar for single plants but solar stations do not have the capacity of fossil fuel stations."

"This movement is complicated by several other factors that means wind does not always flow from the equator in the direction of either pole. The rotation of the earth creates a force known as the Coriolis force and this factor along with the temperature differences create winds at high altitudes above the earth on a large scale. These Geostrophic winds play a part in the wind's that affect us in everyday life, but local winds are largely affected by the surface of the earth - which is neither uniform or smooth. The earth has large flat plains (desert regions), areas covered with plant life (rainforests), very uneven regions (mountain ranges) and very smooth regions (seas and oceans), all of which affect the wind near the surface of the earth to varying degrees. These areas of the earth all have different values of roughness, which can impeded the flow of air. Obviously the lower the value of roughness the less the air is impeded."

""It may surprise you to know that the ancient Romans had central heating. They used geothermal energy - in the form of hot springs - to heat their homes. Geothermal heating wasn't used in an organized fashion since until the late 19th century when Boise, Idaho, piped in water from local hot springs to warm buildings. Now, geothermal energy is used globally. Reykjavik, Iceland, leads the world in use of geothermal energy, heating 95 percent of its buildings with heat from below the Earth's surface." more from curiosity.discovery.com - Not Cached - Edit - Delete - Share▼ - Preview"
