Power Usage Effectiveness (PUE) is a new term in the data center lexicon, comparing a data center's total energy requirement to the energy consumed by the IT load. With 42U's PUE Calculator, a data center operator does not need to know the origin or intricacies of PUE. If the data center manager can access his IT load (from the UPS), and his facility load (from the meter), he receives an initial PUE score. For more detailed calculations, 42U's Energy Savings Calculator makes use of the same formulas to project energy and CO2 savings over one, five, and ten years.
The U.S. Department of Energy is providing Texas with more than $218 million in stimulus funding for state energy programs. To help orient energy efficiency leaders, Green Energy Audit Certification is hosting a class in San Antonio on September 28 to jump start energy audit learning.
Article discusses green plumbing systems, what makes them green, and how to make them greener. Included in the discussion are hot water demand type delivery systems, hot water plumbing layouts and tankless water heaters.
Biofuels are by definition any fuel that, by being burned, can be converted to energy, and that is produced from a biological source. Since a biological source is also a renewable one, biofuels are reproducible. One type of fuel already being produced from biological sources is biodiesel.
Are you tired of paying high power bills? If you are you are not alone. Many people are, and heating your water is about 1/3 of your bill. You can lower your power bill by having a solar power hot water heater. You can even do the installing yourself. That makes even more economical.
Photovoltaic cells-those black squares an array of which comprises a solar panel-are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point. The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce and at once more productive. As far as the aforementioned cost, the price of producing solar-generated energy per watt hour has come down to $4.00 at the time of this writing. Just 17 years ago, it was nearly double that cost.
One of these is solar power. Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced. Solar energy power can be used for electricity, heating, and making hot water. Solar energy produces no pollution, as its input comes completely from the sun's rays. However, much more work still needs to be done in order for us to economically harness the sun's energy. For the time being, the resource is a little too conditional-storage batteries are needed to be used as backups in the evenings and on inclement days.
