North Carolina’s Future: Offshore Drilling & Wind Farms

Filed under: environment, News — Tags: , , , , , , — 4x4RE @ 11:49 am

Tell the Governor What You Think About Offshore Drilling, Wind Farms

North Carolinians have an opportunity to tell Gov. Beverly Purdue what they think about offshore drilling, wind farms and other energy issues that could affect the N.C. coast. The Governor’s Scientific Advisory Panel on Offshore Energy will hold three meetings along the coast next week.  The purpose of the meetings is to get the public’s input on a variety of energy topics affecting the coast. The meetings are set for:

  • Jan. 10: UNC-Wilmington Nursing Building, Room 1051, 4 p.m.
  • Jan. 11: UNC Institute of Marine Sciences, Morehead City, 5 p.m.
  • Jan. 12: Dare County Administration Building, Manteo, 4 p.m.

Appointed in 2009, the panel is scheduled to report its findings in September… read more

Consider attending one of the meetings or submit written comments to the panel. It’s an issue that is very important to the future of our coast.

Green Energy: Wind or Solar?

Filed under: Uncategorized — Tags: , , , , , — 4x4RE @ 1:29 pm

Many people who you talk to about generating electricity at home seem polarized to either wind turbines or solar panels. I found this great article at http://windpowerspot.com that suggests “Why not use both?” For many areas maybe a mixture of both is the best way to handle our energy needs.

Many people today have realized the dream of being completely off the grid by combining wind and solar energy. Small sized affordable wind generators are available today for the home user, and they are being combined with photovoltaic cells for power generation. It’s obvious that fossil fuel energy costs are going to keep on rising making it harder to afford getting power from the grid. The time is more than ripe for solar wind energy to be one of the solutions to rising energy costs, and to take us off of fossil fuel energy dependence.

Wind Turbines

Wind turbines are actually very simple machines. They consist of 3 parts: rotor blades, a shaft, and a generator. The rotor blades act like a propeller that turns the shaft when the wind flows through them. The shaft then turns the generator and a current is generated. About eighty-five percent of all off-grid systems use solar wind energy.

The new micro as well as mini wind turbines are very popular with sailors, and are now starting to be more popular with home owners in Europe and the UK. Mini turbines are very cost effective and will only cost about $1,500 to $2,500. They are perfect for generating electricity if you live off the grid in remote rural areas. It’s satisfying to think about having solar wind energy provide for all your energy needs and also knowing that you never have to depend on utility companies.

Photovoltaic Cells

The typical home solar power system consists mainly of these:
a) Photovoltaic Panels
b) Charge Controller Module
c) Batteries (optional)
d) Inverter
Photovoltaic panels convert sunlight into an electric current. The type of current generated by a photovoltaic panel array is DC or direct current. For this current to be usable in most common households, it has to be converted into AC or alternating current. That’s where the inverter comes in. It’s job is to convert DC into AC current.

Solar wind energy systems are also called hybrid energy systems because the use a combination of solar and wind power to generate electricity. The wind turbines are mostly used during the winter months (in the northern hemisphere) when the sun’s vertical rays are mostly directed toward the southern hemisphere, and days tend to be cloudy. During summer months, photovoltaic cells would supplement greatly along with the wind turbine.

By using hybrid solar wind energy systems, a homeowner has the option of using or omitting batteries for storage. Homeowners also have the choice of being “Grid-Tied” or “Net Metered”. This means that your solar wind energy system has the ability to provide electricity not only for your house, but the power company as well. This way, if your solar wind energy system generated more energy than was used, the energy can be sold back to the power company. When you’re selling energy back to the company, your power meter runs backward. The “net metered” system therefore is highly recommended. The grid also works as your “battery backup” when your hybrid solar wind energy system doesn’t provide for your power demands.

Net-metered systems are also recommended because they are easier to install, cost less, and offer better performance.

Ways we can harness the wind without without big wind farms.

Filed under: Uncategorized — Tags: , , , , — 4x4RE @ 3:37 pm

When people think of wind power they think enormous windmills on gigantic towers. Many wil agree that they work well in certain areas, but are unsightly. Who wants to have this beside their neighborhood?

or this view from their beach?

But today may creative minds are coming up with new ways to integrate wind turbines with our communities that are not only more aesthetic, but in some cases almost artistic.

Take a look at some of these:

Turbines powered by the turbulence created by cars.

Turbines atop of street lights.

Vertical Axis Roof Mounted Wind Turbines

By turning our energy problems over to the creative minds that are now emerging, we stand a chance of not only concurring our demand for fossil fuels but of finding more appealing ways to become stewards of our planet.
