SmartGrid and Renewable Energy: The Unresolved Questions

Wind Turbine Farms As the electricity industry forges ahead in defining and ultimately implementing SmartGrid and transitioning to a supply portfolio that includes renewable energy sources, there are a number of unanswered questions and obvious objections that must be confronted to ensure the full benefits of improved reliability, increased energy efficiency, and reduced CO2 emissions.  These...

Impact of Renewable Energy on Electric Transmission

Renewable Energy Impacts Transmission Grid Wind Power - Alternative/Renewable Energy The anticipated increase in renewable electric power generation (particularly wind power) will most likely be satisfied by the trend toward non-utility companies building only transmission facilities.  These trends are: Largely driven by the advent of independent power producers (IPPs), vertically integrated...

The Inevitability of Smart Grid

Expansion of Driving Forces Point to Smart Grid Wind Turbine Farm Much of the current industry discussion around Smart Grid tends to focus on its benefits related to improved environmental stewardship through energy conservation and the introduction of renewable energy resources. Although these benefits will have a permanent role in the overall business case for Smart Grid investments, there are...

Crude Oil Pricing

Oil Rig Crude Oil or petroleum, the “black stuff” that comes out of the ground, is made up of a variety of elements such as carbon, hydrogen and sulfur, and originates from the remains of plants and animals that existed in prehistoric ages. Hence, it is commonly referred to as fossil fuel. However, crude oil must be refined to produce energy, whether in the form of gasoline, kerosene or...

The Peak Oil Debate – Does it Matter?

Establishing the Context The theory of peak oil implies that there will be a time at which global oil production begins a permanent decline as a result of supply and economic production factors. Should world demand continue to increase (as it has), the point of peak oil will pose a significant supply and price problem for the world economy. The question we seek to explore is, “Have we reached...

Reducing Home – Related Energy Costs

In reviewing the electricity price trends over the past 50 years (refer to figure 1) real electricity prices are at a level consistent with the industry’s lowest real level of the 1960s. Since many consumers are interested in reducing their overall household costs, there are certainly opportunities to reduce costs related to the use of electricity. However, the first step requires an...

Fundamentals of Electricity

Fundamentals of Electricity As we build the energy authority website, we remain mindful that many of our readers might benefit from a tutorial of the terms and concepts around each form of energy. So, interspersed among our articles will be writings addressing some of the more basic elements of the principles involved. This article deals with those that underlie electricity. Electrons – The...

Home Appliances – Energy Consumption vs. Conservation

Refrigerator/Freezer According to the EIA, U.S. residential, commercial and industrial customers consume 25 percent of the electricity generated worldwide, with more than 30 percent of that consumption, or 1.14 trillion kWh, used in homes. This seemingly high level of energy consumption in the residential sector can be attributed to the energy required to operate home appliances. Even though the...

Lowering Heating Bills – A Simple Proposition
