Wave and Tidal Power to Generate Electricity

It’s not a new idea, but until now technology was insufficient to realize wave energy projects in industry sizes. Long stretches of western coastline open to energy-laden North Atlantic waves and tides make Scotland a very good place for developing wave and tidal power generation systems. The long-lasting marine renewables industry is booming right now, or it will for sure in the coming years. These investments are very capital-intensive they depend on building large wave and tidal power systems on enormous territories that connect into a grid... This is one of the reasons why progress has been limited.

Estimations show that systems built on the west coast of Scotland could produce up to 20 gigawatts and an average of 80 terrawatt-hour per year! Holy cow, that is 1/5 of UK’s total electrical consumption! Hydro and wind take up large portion of installed renewable power sources, including biomass to electricity and biomass heat, Scottish Renewables states in a recent statistic publication.


Major companies invest in wind and solar farms instead of wave and tidal plants. Private investors and large multinational companies don’t like to risk: they stick with something that is working already, no matter what developers of marine renewables demonstrate (like the aforementioned study that would guarantee 1/5 of UK’s consumption from renewable source without the need to sacrifice croplands or meadows!).

It is good to know though, that there are already future plans and alternatives to current-alternatives like wind and solar power (no matter how odd this may sound). These last ones are available for end consumers also like you and me, and if you want to know how to harness them to eliminate your power bill, click on the link found at the end of this article!

Energy Saving Light Bulbs - The Sensible Alternative

he lights in an average household use about 20% of the total electricity, so anything that will reduce that power consumption will help lower your energy bill while cutting down on pollution. Fortunately, it’s easy to save energy on lighting by simply installing energy saving light bulbs.
Regular incandescent light bulbs produce light by heating a small filament inside the bulb. This heat production accounts for 90% of the energy they consumer. Energy saving light bulbs are florescent, much more efficient because they don’t need heat to produce light.


How much energy do they save? On average, the energy savings are about 66%. But that is not the only way you save money using these bulbs. They also last much longer than regular bulbs, so although they cost more, you still save money when buying light bulbs.

Energy saving light bulbs last about 10 times longer than incandescent bulbs. Even if the florescent bulb costs considerable more than the traditional bulb, the lifespan of the bulb combined with the energy savings adds up to substantial savings.

It has been conservatively estimated that you can save about $4 per year for each energy saving light bulb that you install in your house. If you replace 20 bulbs, that’s a savings of $80 a year.

Just imagine if every household in America took advantage of the savings that compact florescent bulbs provide. Not only would have more buying power, we would also cut down on the pollution caused by electricity generating plants.

Greenhouse emissions are one of the biggest concerns with burning fossil fuels to produce electricity. The average household produces more greenhouse gases than a car because of the amount of electricity consumed. Installing energy saving light bulbs is one way to cut down on those emissions.

Do your pocket book and the environment a favour by using florescent compact bulbs wherever you can. It’s the only sensible thing to do.

The History of Electric Cars

We've all seen the commercials talking about how technology was all going to be about flying cars and cold fusion. In reality, though, we have our very own science-fiction-turned-fact in looking at hybrid vehicles which are taking over. They truly are efficient and are money-saving at some levels, but most consumers assume that the concept of electric motors is brand new, but the first experiments with electric motors began in the mid-1800s. Going as far back as 1832, locomotives and carriages were already using electric motors, considering that lead-acid batteries were already being used.

In the 1890s, though, the first electric cars were actually built at home in the U.S. and actually shown to the general public. To thank for that first electric car we have William Morrison, whose electric car was one of the first to be successfully tested. By the time 1893 had rolled around, there are already several models of electric-powered cars that were showcased in Chicago.

If you have the impression that electric cars are solely known to the public as the new economic fad, think again. Made by Pope manufacturing company in New York City, 1897 saw electric taxis around the city. In fact, by 1899, Thomas Edison was also involved with these ideas, even though he never saw his developments come to fruition.

In 1900, 28% öf vehicles in the U.S. were powered by electric motors, and over one-third of the driving populations in New York City, Boston and Chicago were actually driving electric cars. Had Henry Ford's new automobile, the gas-powered Model T Ford, not come along eight years later, the electric car could have possibly been the more common vehicle. Unfortunately, Henry Ford's Model T had taken over electric cars by far by the 1920s.

Around 1966, environmental awareness actually became a concern, prompting the US Congress to actually pass legislation regarding pollution, air cleanliness concerns, not to mention rising gas prices. As a result, the popularity and demand for electric cars has increased.

While most consumers think of old hybrids as being the 1998 Toyota Prius, the first actual hybrid vehicle was constructed from a Buick Skylark by a man named Victor Wouk in 1972. The Federal Clear Car Incentive Program in 1970 brought forward this need for hybrid cars, and Wouk's hybrid was no different, having been built specifically in response to this Act. Later, in 1974, Vanguard-Sebring built an electric vehicle known as the CitiCar, and was another attempt to respond to the Incentive Program. Unfortunately, the company and program were both out of the picture by 1980.

Although there was an actual act passed by Congress to research and develop hybrid vehicles in 1976, General Motors didn't actually start its research on their first hybrid vehicle, the EVI, until 1988. Thankfully, the entire country got a kick in the pants when California passed a Zero Emission Mandate in 1990 that required at least 2% of vehicles be ZEV compliant by 1993, and then 10% of those vehicles by 2003. Unfortunately, both of those goals had not been met by 2003, which still left the country in a position to research hybrids.

Finally, in 1997, Toyota was able to make a breakthrough, and the Toyota Prius was released to the commercial mass-market, selling over 18,000 vehicles in one year alone. It didn't take long after that, and in the next three years, Chevy, Toyota, Nissan, Ford, and GM began to release hybrid vehicles, but they were full of kinks and problems. By 2004, most of them were scrapped and recycled.

In 2006, hybrid vehicles began to see a resurgence in production. This time, the kinks were worked out and now, hybrids will soon become the new standard. The fact of the matter, though, is that while the packaging may be new, the actual technology behind the hybrid has spent a century being developed.

Comparing Hydrogen Powered Cars To Electric Cars

With gas prices being so high, alternative fuel vehicles have become a popular topic. Two of the types of vehicles that tend to get a lot of press are the hydrogen fuel cell powered vehicles and electric powered vehicles. Both are lauded as the way of the future

But which of these two options are really has the better chance of being the car your children drive.

Let’s look at hydrogen fuel cells first. When burned in an engine, the only emissions giving off is water, so a hydrogen powered vehicle is a zero emission vehicle. Hydrogen is also a better fuel than gasoline, it actually has the highest energy content per unit of weight of any known fuel.

Hydrogen is also a very abundant element. While current methods for making hydrogen are done by using fossil fuels, such as natural gas, coal, and oil, American wouldn’t be dependent on foreign oil anymore. Also, hydrogen can be extracted from water, and we all know there’s a lot of water on this planet.

However, hydrogen is not without its share of drawbacks. Probably the biggest problem right now is that it would require an entire new infrastructure. While gas stations could be outfitted with hydrogen fueling stations that would take years. Also, the technology to store hydrogen efficiently is still not ready for prime time.

Then there’s the electric car. Electric cars can also be considered zero emission vehicles since they give off no emission when running. However, electric cars do require power from the electric grid, which does give off emissions. As the electric grid gets cleaner, though, so do electric cars, and electric powered cars are substantially less polluting than gasoline powered cars due to the fact that power plants are far cleaner and more efficient than an internal combustion engine in a vehicle.

The technology for mainstream electric cars is also not quite ready for all the major manufacturers to stop making gasoline powered cars, but it’s much closer than hydrogen currently is. The challenge with electric cars right now is the batteries. The batteries are both expensive and current models, like the Tesla Roadster, have a range of only 250 miles – great for commuting, but not so good for road trips. The other problem is the length of time these vehicles take to charge. It’s not simply a matter stopping at your local power station and plugging in for five minutes and leaving. A typical charging cycle for current prototypes is 4-5 hours – again, fine if you’re commuting, but impossible for a road trip. While technology is being developed to make charging your vehicle as quick as quick as filling up with gas, it has a ways to go before it’s ready, just like hydrogen fuel cells.

Fleets of electric cars will certainly be hitting the roads sooner hydrogen fuel cell cars, but which one ultimately ends up being the vehicle of choice for American drivers remains to be seen as both have plenty of challenges to overcome before people will readily give up their cheap gas powered cars in favor of these alternatives.

New Tools to Help Reduce Electric Bill Amounts


As utility costs continue to increase, chances are you are doing all that you can to lower the amount of energy you use in your home. Both electricity and gas bills are a concern for many families today. While there are some things you can do around your home, like turning off lights or lowering the thermostat in the winter, sometimes you will need some outside help to find a way to lower electric bill amounts.
There are several tools you can use to reduce electric bill costs and save power. One option you can use is the high efficiency light bulbs that are becoming popular. These light bulbs provide as much light as incandescent bulbs do, but they last longer, thus creating less waste. They also use far less electricity than traditional bulbs. These bulbs use around a quarter of the amount of electricity that standard bulbs do. For instance, a 25-watt compact fluorescent bulb provides as much light as a 100-watt incandescent bulb. By replacing the incandescent bulbs in your home with these higher efficiency light bulbs, you will save power.
The Power Save 1200 is another option you can use to lower electric bills for your family. The Power Save 1200 reduces your electricity consumption by actually reducing the wasted electricity in your home. While you can control some electricity waste, such as the electricity you waste when you leave a light on, some wasted electricity is unavoidable. When electricity runs through the wires and the appliances in your home, some of it converts to heat. The heat is wasted power. The Power Save 1200 helps to eliminate this form of wasted power. The Power Save 1200 is a box that you place by your breaker box. It contains transformers that can store and release electricity to some of the items in your home. Specifically, the Power Save 1200 can help power motors in your home.
When something with a motor in it, such as your air conditioner, needs to run, the appliance or device sends a signal to the transformer at your utility company's box requesting the power it needs. This request must travel through the wiring in your house, your circuit panel, the meter, and all the way to the transformer. This path creates a lot of heat, which is wasted electricity. However, when you have a Power Save 1200 installed, the request for power will stop at the Power Save 1200 device, because it has the electricity stored that your device needs to begin running. This reduces how much is lost to heat. In fact, this device can lower electric bills by as much as 25% when used correctly. On top of the money you will save, you will also notice that the items in your home that contain motors last longer, because they do not heat up as much as they did before you installed the device.
Finally, consider installing solar garden lights in your outdoor living space in your quest to lower electric bill amounts for your home. These lights will provide the amount of light you need for your outdoor space, without any electricity. They absorb the light from the sun and convert it to electricity. At night, they light up and provide the light you need along your walkway or in your garden. If you use enough of them, you may be able to stop using your porch light, thus saving power for your home.
They key to lowering electric bills is using common sense and installing the devices that can help reduce your electric consumption. While some of these devices seem as though they cost a lot at the time of purchase, keep in mind that they provide continued savings month after month on your electric bill. Not only that, but they also help protect the environment. We can all take steps to save power, and installing some of these devices is one way you can do so.
Ken Potter is the founder and owner of http://www.usaveonelectric.com/, where you can buy the Power Save 1200, which can lower electric bills up to 25%. This site also carries the Power Save 3200 and Power Save 3400 Units for Commercial use.
