Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Keeping It Simple

Keeping It Simple
ABB CEO Ulrich Spiesshofer began his March 3 keynote address at Automation & Power World with a family anecdote about his mother's response to his being appointed to his current position. After listening to him explain what ABB does-for several minutes-she interrupted and asked, "that's very nice, son, but can't you explain all of this in simple terms?"

Mrs. Spiesshofer would probably have approved of the one-sentence definition of ABB's business that her son delivered to the audience in Houston.

"ABB provides power and automation solutions to utility, transport and infrastructure, and general industry customers, and we do it globally."

It doesn't get much simpler than that, but this straightforward description maps to a global market of 600 billion today, with projections running to more than 750 billion by 2020. As Spiesshofer noted, ABB is "well positioned in attractive markets."

Look no further than North America, where the company has deployed more than 10 billion in capital over the last five years. Baldor (motors, mechanical power transmission), Ventyx (enterprise software), Thomas & Betts (low-voltage products) and Power One (solar inverters)-these major acquisitions combined with organic growth in the region have fueled a 120 percent growth in sales between 2010 and 2014. Over the same time period, engineering sites proliferated from around 30 locations to more than 100 while overall headcount jumped 125 percent.

Americas President Greg Scheu followed with a brief presentation that fleshed out the regional story, with particular emphasis on the US. He provided several compelling examples of how the "big shifts" in power (e.g., microgrids, renewables, new business models) and automation (e.g., internet of things, analytics, advanced manufacturing) are manifesting in what remains ABB's biggest growth market.

In power, for example, Scheu cited an innovative energy storage project ABB completed at SEPTA, the Philadelphia-area transit operator. A battery energy storage system captures energy from braking trains not only for use on the SEPTA system, but also to provide frequency regulation services back to the surrounding grid. In Alaska, ABB delivered a microgrid solution that allowed Kodiak Island to accommodate economic growth (i.e., the installation of a larger crane at the main port) using virtually 100 percent renewable power.

But Scheu was quick to point out that there is still much that can be done to improve efficiency and productivity in traditional businesses, too. He pointed to a new steel plant being constructed in Arkansas by Big River Steel where ABB is supplying high-efficiency Baldor motors as well as drives, transformers and rectifiers. The 1.3 billion greenfield project is proof that manufacturing, even in basic materials like steel, can still thrive in North America thanks to advances in efficiency and flexible plant design.

If there was one takeaway from both executives' remarks it was that ABB has a lot of room to run in some very lucrative markets. And even if it wasn't stated expressly, it's clear that the company's focus on its core competencies of power and automation has paid off.

Who Should Consider Green Energy

Who Should Consider Green Energy
Whether you own a business that you would like to power with a green energy source, own a home and want to be more independent when it comes to powering your home, or are part of a local government that would like to bring an efficient and economic source of energy to your community, chances are you should be considering green energy. Let's look at some reasons why.

DETAILS

* UNIVERSAL BENEFIT. The planet belongs to everyone, and protecting it is the responsibility of each of its owners. Green energy benefits the planet, which in turn benefits everyone now and in the future.

* CLEAN ENERGY. Green energy is clean energy. There is no danger of toxins polluting the ground or water due to a spill, and fumes and gases aren't released to pollute the air.

* SHOWS RESPONSIBILITY. If you own a business, then using sources of green energy demonstrates that you are taking responsibility for the impact on the environment that your business could have.

* REDUCE OIL USE. Oil is a fossil fuel, and its supply is limited. A low supply will send prices skyrocketing, and it will eventually run out.

* LOWER UTILITY BILLS. When hooked to a power grid, the average home spends more than 100 per month for electricity. Solar energy used to replace some or all of your power grid electricity will dramatically lower your costs for utilities.

* BETTER BUSINESS PLANNING. Utility bills fluctuate considerably during the various seasons, and the prices of fossil fuels can go up over a period of just a couple of weeks. With green energy powering your business, you have the ability to make a better estimate of power costs each month.

* Green sources of energy are renewable so there's no danger they'll run out, unlike with fossil fuels.

* Your home or your business could have a constant source of power, even during winter storms or blackouts that take down the power grids.

* Once you have installed solar panels, a wind turbine, or other source of green energy, there are no costs for fuel to run your source.

* BENEFITS DEVELOPING COUNTRIES. A combination of solar and wind power can bring electricity to the millions of people in developing countries who don't have the resources to use fossil fuels or power grids.

* Using green energy is practical because the sun, wind and water are widely available and provide clean, efficient energy.

* A windmill farm or other source of green energy can provide consistent, clean energy for a whole community consisting of hundreds of homes.

* Fossil fuels must be purchased from the countries that have supplies of coal, oil, etc. By using wind, the sun, biomass, water and other sources of green energy, every area of the world has what is needed by using combinations of multiple types of green energy.

* PROVIDES JOBS. A community that decides to build one or more wind turbines, solar energy plants, or other sources of green energy will stimulate the local economy by providing jobs.

* SAVE ECOSYSTEMS. The burning of fossil fuels emits carbon dioxide and other gases that cause the atmosphere to trap in the sun's heat, raising temperatures and negatively impacting ecosystems throughout the world.

THE BOTTOM LINE

Green energy benefits everyone, and by switching to a source of renewable energy, you are reducing the amount of damage you cause to the environment while reducing your costs for heating and powering your home. If you own a business and switch to green energy, then the benefits will likely be on a larger scale. Essentially, everyone should consider green energy.

An Integrated Assessment For Wind Energy In Lake Michigan Coastal Counties

An Integrated Assessment For Wind Energy In Lake Michigan Coastal Counties
The benefits and challenges of onshore and offshore wind energy development were assessed for a four-county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost-effective with contract prices less than the benchmark energy price of a new coal-fired power plant. Constructing a 100 MW wind farm could have a 54.7 million economic impact. A patchwork of township-level zoning ordinances regulates wind energy siting. Voluntary collaborations among adjacent townships standardizing the ordinances could reduce regulatory complexity. A Delphi Inquiry on offshore wind energy in Lake Michigan elicited considerable agreement on its challenges, but little agreement on the benefits to coastal communities. Offshore turbines could be acceptable to the participants if they reduced pollution; benefited coastal communities; involved substantial public participation; and had minimal impact on property values and tourism. The US Coast Guard will take a risk-based approach to evaluating individual offshore developments and has no plans to issue blanket restrictions around the wind farms. Models showed that using wind energy to reach the remainder of the ten percent renewable energy standard could reduce SO2, NOx, and CO2 pollution by 4-7 percent. Turbines are highly likely to impact the area's navigational and defense radar systems but planning and technological upgrades can reduce the impact. The integrated assessment shows that responsible wind energy development can enhance the quality of life by reducing air pollution and associated health problems and enhancing economic development. Policies could reduce the negative impacts to local communities while preserving the benefits to the broader region.
