On the eve of Super Bowl 2015, most people are making plans for watching the big game and eating wings. Here at energytrends.org we are taking a look at the carbon footprint of this annual, all-American tradition. The National Football League (NFL) has made efforts in recent years to offset the energy consumed at the…Read More
A new study from the National Renewable Energy Laboratory (NREL) has recognized the western states with the most potential for renewable energy projects. With states’ renewable portfolio standard (RPS) requirements all reaching maturity by 2025 it looks beyond and predicts who will be the renewable energy leaders to come.
The primary renewable energy resources that were investigated were wind power, solar and geothermal. Not surprisingly, Wyoming was listed as one of the top producers of wind power especially when you consider their new wind energy project. Additionally, New Mexico was highlighted as a wind power giant. According to Thomas Stackpole, “By 2025, New Mexico could be producing twice the amount of renewable energy as its required to, meaning it could start selling it to other states.”Read More
Colorado State Capitol Building First Capitol Building to Implement Geothermal System for Heating/Cooling
The Colorado State Capitol in Denver has become the first State Capitol in America to implement a geothermal heating and cooling system. The system is expected to save $100,000 in heating and cooling costs in the first year alone. It consists of two wells drilled more than 850 feet underground into the Arapahoe Aquifer. The state capitol in Idaho is the only other to run on geothermal energy but it is only able to provide heat by tapping into hot springs.
Chevron Energy Solutions built the well under the state capitol and created an open-loop geothermal system that pumps the water directly into a building pump unit that can be used for both heating and cooling. In addition to upgraded functionality, the project eliminated the need to update the outdated (dating back to the 1940’s) pumps andRead More
Geothermal wells are traditionally drilled in locations where hot and permeable rocks make it easier for underground liquid to heat up. Throughout the country there are hot rock formations that have the potential to produce energy but lack either permeable rock or adequate water underground to produce the hot water and steam. This is where Enhanced Geothermal System (EGS) technology enters the scene.
EGS technology, explained in more detail here, is a man-made process that injects fluid underground to create reservoirs, causing pre-existing fractures to re-open thus creating permeability. Fluid circulates throughout the hot permeable rock which createsRead More
How much water does the typical American use on a daily basis? According to the Environmental Protection Agency (EPA), approximately 100 gallons of clean, drinkable water is used, 15 gallons of which is for cooking or consumption. The rest is used for things such as showering and flushing toilets.
A homeowner in Michigan, with the help of a group of engineering students at the University of Michigan, have taken on a challenge to retrofit a 110-year-old VictorianRead More
According to a study produced by an interdisciplinary panel from the Massachusetts Institute of Technology, geothermal energy in the U.S. has the potential to have an installed capacity of 100,000 MW within the next 50 years. Currently, installed capacity is 3,187 MW in the U.S so there is clearly a long way to go.
There are currently numerous set backs in geothermal development such as the high cost of exploring possible geothermal sites and the hefty drilling costs. On the otherRead More
