Green Renewable Energy

Get eco in your kitchen with these tips. From electricity, to water consumption, your kitchen can be earth-happy if you follow some simple guidelines to re-use items, minimize waste and be as environmentally friendly as you can.

Microwave - Cooking in the microwave and other small appliances can be extremely efficient compared to a stove. When buying one, go for models with the highest energy star rating.

Bamboo and aluminium steamers - Bamboo or aluminium steamers are perfect for conserving energy. Always try to combine cooking time and energy. For example, a roast and vegies can both be cooked in the oven at the same time, while a pot of pasta can also be used to steam vegies.

Food processor or blender - Making your own sauces, dips and dressing not only saves money, it’s healthier and drastically reduces packaging.

Eco bags - When you get back from the shops, put your eco carry bags back into your car or handbag to avoid forgetting them next time. Many eco-bags are made from a light weight parachute material that is easy to compact and stow away.

Water efficient fittings - As has become the standard, it is a great idea to install water=saving devices throughout the home - especially in the kitchen where taps are used the most.

Pots of herbs - Plants herbs in pots and place them close to your kitchen. That way, when you need some fresh herbs, they are already close at hand.

Recycling - Set up a system to separate your waste. Separate plastics, glass, newspaper and cans. Put a calendar up to remind yourself when different items are collected and contact your local council for more information.

Compost Pail or Bokashi bin - Invest in a small compost pail or in a bokashi bin to collect your kitchen scraps. By keeping your compost pail close by, it’s easier to collect scraps as you go and then add them to your garden or composting system later.

DIY cleaning products - ditch the chemicals and make your own cleaning products. Mix white vinegar with water for a terrific floor cleaner and add a touch of lemon for a fresh scent.

Leftover fridge calendar - Keep a calendar on the fridge to mark your leftovers. This way, you can tell at a glance if you really need to do another shopping trip.

Plastic tub - Don’t have a grey water system? Use a plastic tub in the sink to catch water from washing vegetables. If you use a grey water safe dish detergent, you can gather the water you use from rinsing your dishes as well.

Coffee and tea - Use fair trade, organic or rainforest alliance coffees where ever possible. Same goes for teas. Always go for loose-leaf teas brewed in a pot or plunger - less packaging.

Kettle - Go for the most energy efficient model. Look for ones that shut off after the water is boiled and remember to only boil the amount of water you need to avoid re heating unnecessarily.

Great place for Alternative Energy ideas

1. Start by switching to green power

   The easiest way to switch to green energy is to call your current provider and see if they offer an alternative. An increasing number of companies do, harnessing renewable sources like wind and solar power to offer electric service in their markets. This costs more for the consumer, since you’ll pay a premium to offset the money involved in tapping the alternative source, but the price varies: in Sacramento, you’ll pay 5 cents per kilowatt hour or $30 a month for solar, and in Oregon you’ll shell out only .8 cents per kilowatt hour for wind, geothermal, or hydropower. Curious about the options in your state?

2. Plug in to solar power

   There are two kinds of solar power you can use in your home: active and passive. Active solar power is captured through solar cells (also known as photovoltaics), and then stored to later provide heat or electricity-or to supplement a traditional heating or electrical system. But before you buy a solar system for your house, keep a few points in mind: many towns have restrictions on the size and type of collectors they’ll allow; the annual number of sunny days in your climate will affect how much power you can collect (the Southwest usually has the best luck with solar collection); and the system’s cost efficiency varies based on its size, your location, and the amount of power you plan to get from it.

3. Get passive solar to work for you

   The second kind of solar power, passive solar, doesn’t involve the (expensive) photovoltaic cells and mechanical systems of active solar, but still takes advantage of the sun to heat your home in one of three ways: direct gain, which collects light through the windows; indirect gain, which stores thermal energy within the walls; and isolated gain, more commonly put to use in a solarium or sun room setup. By thinking about window placement, insulation, and even landscaping–trees can be the ultimate passive solar helpers, since they soak up solar in the hot summer, and let the sun through in the winter—it’s possible to help keep your home warm in the winter and cool in the summer.

4. Opt for solar hot water

   You can also use solar power to heat the water for your showers, dishwasher, and laundry (though why aren’t you using cold water for that?) by installing a solar hot water system. If you live in a place where freezing temps aren’t a concern, look for a direct circulation system-this cycles water through the solar heater and into the home; otherwise, go for an indirect circulation system, which runs a freeze-proof fluid through the system to prevent icing. Both those active systems are generally more efficient than passive solar heaters, which don’t have the same pumps and controls but can be more dependable. No matter which system you choose, you’ll want to consider a (smaller) more traditional hot water heater for backup on days when the sun won’t come out or for showering during peak times.

5. Tap into the earth’s natural geo-energy

   The terms “geothermal” and “ground source heat pump” are nearly interchangeable in casual conversation-but they shouldn’t be, since they’re not the same. Geothermal energy comes right from the ground-think hot springs, geysers, and volcanic areas—while ground source heat pumps use the relatively steady temperature of the Earth (as compared to the air) to heat and cool buildings. These heat pumps use as little as half as much electricity as traditional systems, and generally last between 25 and 50 years; while they are more expensive to install than other systems, you can expect the system to pay for itself in energy savings in less than 10 years.

6. Replace oil with biofuel

   You can also heat your home using biofuels—nontoxic, biodegradable, and renewable power sources, like those made from animal and vegetable fats and oils or wood. If you’re using oil heat, have a technician take a look at your furnace and get the okay to switch to a blend of 20%-99% biodiesel; in most cases, you won’t need any additional parts or service to make the switch. Using a woodstove to heat your home is an age-old solution, but the more modern version is the pellet stove: The pellets of compressed sawdust take up less storage space than a wood pile, and burn with so few emissions that they aren’t required to get EPA certification. (One tip: if you’re going this route, find a local source for inexpensive pellets first.)

7. Harness the power of the wind

   Wind energy is one of the cleanest forms of alternative energy available, and using it can cut your electricity bill by as much as 90 percent. Once you make sure your area is zoned to allow wind turbines, you’ll want to make sure you have enough space—the Department of Energy Efficiency and Renewable Energy suggests at least one acre of rural land—and a climate that affords a steady breeze. Run an energy audit on your home to determine what size turbine you’ll need; most houses require between 5 and 15 kilowatts to produce an average of 780 kilowatt hours every each month. And wind turbine systems aren’t cheap, so run the numbers to figure out if you’ll save enough to make the 20-year investment worth it.

8. Capture small-scale hydropower

   Before you can use hydropower for residential energy, you’ll need one very important jumping-off point: running water on your property. If you are lucky enough to have a creek, stream, or river in your backyard, then a micro hydropower system may be a good alternative energy solution. By diverting a portion of the water through a wheel or turbine, you allow a shaft to spin; the spinning allows immediate results, like pumping water, or more indirect usage, like powering a generator. These calculations from the Department of Energy Efficiency and Renewable Energy can help you figure out if your water source will provide enough energy to significantly offset your electric bill.

9. Make a smart start

   If you’re in the process of buying a home, it’s easier to make alternative energy work for you, by buying a property that comes with running water or room for wind turbines, for example. If you’re designing from the ground up, choose a roof that’s specially fitted for solar panels; place your house on the lot so it takes advantage of the sun; build with passive solar materials; and use daylighting technology by installing windows and doors in places that allow you to get the most out of natural light sources,and to go green.

10. Think smaller

    If you can’t make the jump to powering your entire house with alternative energy, start by focusing on one room at a time. Or look even more closely at your life, and get small solar cells to charge your laptop, cell phone, iPod, and other small gadgets—every little bit helps!

Great place for Alternative Energy ideas

Almost every day, one can find an article online or on the news or in print about the environment, living “green”, pollution and the changing climate. While these articles deal with environmental issues on large scale perspectives, there are a number of aspects of the current state of the economy and environment that affect and are influenced by the average middle class citizen.

A good example of a current economic and environmental trend today is the growing popularity of the use of renewable energy sources to provide some if not all of the electrical power in private homes. While solar power is a very popular alternative renewable energy source, many people are also turning to wind power and wind generators to provide them with affordable electricity.

In many Midwest states, one can see examples of the large electric cooperatives using wind power to generate significant amounts of electricity. This wind power is produced by large “farms” of massive wind generators. These generators are essentially oversized propellers mounted on top of very tall towers. The wind turns the propellers which provides the kinetic energy which is turned into electricity.

All of these large generator farms are located in rural or semi rural areas. However, it is possible for people who live in towns and cities to have efficient wind generators. The residential wind generator is simply a downsized version of the larger generator. Most residential wind generators are mounted on top of 20 to 30 foot tall towers or on top of shorter towers mounted on the roof of the house. The tower is much less obtrusive than one would think and many are painted to blend in with the color scheme of the house. In some cases, zoning laws might restrict exactly how tall of a tower one may have, but in almost all cases the wind generator can be adapted to conform to the regulations.

Just as with solar panels, the wind generator can be tied into the house’s electrical system and can provide electrical power directly to the house. While it is not generally advisable to try to go off the grid with a wind generator, one will usually be surprised at how much power it can produce on even a fairly calm day. The power the wind generator provides will be applied as a credit on the house’s electric bill, and in many cases will be sufficient to zero out the bill. This can save a family thousands of dollars per year and also has the effect of reducing pollution by indirectly reducing the amount of fossil fuel needed to power the electrical grid.

In all, installing and using a residential wind generator is a smart move for financial and for environmental reasons. With the savings one will get from the reduction in utility costs, many people will be able to recover the cost of the system in the first year alone, and in some cases, there are tax credits available for people who make energy efficient improvements to their homes.

We are constantly trying to find new ways to be environmentally friendly and wind generators are the perfect way to create renewable energy that’s good for the environment. One wind generator that is fast becoming the favorite of many is the Phoenix 300 Watt Wind Generator.

This generator is handy because it’s both small and compact which makes it very easy for anyone to install. It now has a new design and only weighs 12.5 kg which makes it easier to transport when compares to other larger more bulky previous models. The blades for this generator are made out of carbon fiber and with the new design all the parts have been made solid.

The Phoenix 300w wind generators are perfect for farms, rural and urban houses. Once installed, they can easily produce 500w output of electricity in no time which will definitely help you save money on your monthly electricity bill.

With the relatively low price of approximately US $690.00 per unit not only are you saving money, you are actually helping reduce green house gases by using wind power which is a renewable energy source to generate your electricity.

Generating electricity from the wind will help you save money on your electricity bill, and it is definitely an ideal solution for people who live in regional areas where main power isn’t as cost effective or reliable as the Phoenix 300w wind generator would be.

This machine can supply you with 50kwh per month when it has good wind conditions and average wind speeds are 12m/s and 210 wind hours.

If you need more information on the Phoenix 300w Wind Generators, please visit the website: www.WindGeneratorsToday.com

Wind power is an excellent weapon for fighting climate change because wind generation produces no carbon emissions at all. When you consider that every unit of energy generated by wind, is a unit of energy free of carbon pollution, wind makes sense. Producing just 10 per cent of electricity from renewables could cut carbon emissions by 2.5 million tonnes a year.

Small wind-electric systems can provide electricity to remote sites, or to houses that are also connected to the utility grid. But the prices! A small turbine can cost $US 2,000! A medium turbine $3,000! A large one can cost $8,500 - and that’s without the rest of the equipment you will need, and installation costs! Although wind systems require some attention, if you build a strong system, following a proven design, wind-electric systems make great economic and environmental sense.

How much FREE electricity will I get? There seems to be a myth that wind power produces little power. Strange, when a 1.8-megawatt turbine produces enough power for 1,000 homes.

More realistically for the DIY wind turbine maker, a small wind turbine, with a rotor diameter of 7 feet (2.1 m), and a swept area of 38.5 square feet (3.6 m2) will produce, per month, at average wind speeds of 10 mph - 80 KWH! This is enough power for a low-energy home, yacht, or business. A medium sized wind turbine with a rotor diameter of 10 feet (3 m) and a swept area of 79 square feet (7.3 m2) will produce, per month, at average wind speeds of 10 mph - 130 KWH! This would be suitable for a medium-energy home, business, or school. A large wind turbine with a rotor diameter of 12.5 feet (3.8 m), and a swept area of 120 square feet (11.2 m2), will produce, per month, at average wind speeds of 10 mph - 230 KWH! This is for big energy consumers. A huge wind turbine with a rotor diameter of 56 feet (17 m), and a swept area of 2,462 square feet (229 m2) will produce, per month, at average wind speeds of 10 mph - 5,060 KWH! These power large farms, very high-energy businesses, villages, islands, and massive heating projects.

Smaller turbines can be built for boats, caravans, cabins, or where only a small amount of electricity is needed. But for significant amounts of energy, you need a large enough rotor, as this is the wind turbine’s ‘energy collector’. When sizing a wind-electric system, you don’t add windmills in as you need them, as you can with solar panels. Because wind is more cost effective as you increase in system size, most people put up only one wind turbine, big enough to significantly slash their electric bills, or to fulfill all of their energy requirements for the foreseeable future.

System Components: The turbine is only one component of a wind-electric system, and very often is not even the most expensive component. You need all of the necessary components to have a functional system. Plan ahead to buy quality components properly matched to each other and to your energy use.

A complete wind-electric system includes: • Turbine—blades + hub = “rotor,” which is the “collector” of the system. • Tower—supports the turbine, getting it up out of the turbulent zone created by trees and buildings, and exposes the turbine to more wind • Wiring and conduit—carries the electricity down the tower and to power-conditioning equipment • Controller/Electronics—controls charging of battery or input to inverter • Batteries—used for storage in off-grid systems or grid-tied systems with battery backup • Inverter—converts direct current (DC) electricity from batteries or rectifier to alternating current (AC) for home use or “storage” on the utility grid • Metering—allows user to understand and manage system operation.
Small wind turbine: needs a controller or inverter, and is suitable for battery less grid-tie or 12, 24, 48 VDC battery charging
Medium sized: needs a controller or inverter, and is used for charging 12, 24, 48 VDC batteries Large: needs controller, dump load, and inverter. Suitable for battery less grid-tie or charging 48 VDC battery.
Huge: suitable for battery less grid-tie

How does a wind turbine actually produce electricity? The rotating blades convert the wind’s kinetic energy into rotation in a shaft. The rotating shaft turns an alternator, which makes electricity. The electricity is transmitted through wiring, down the tower, to batteries, or an inverter. The blades are designed to intercept wind and capture its energy. Most modern wind generators have three blades, to compromise between the highest efficiency possible (one blade) and balance (multiple blades). The blades must turn to face the wind, so a yaw bearing allows the wind turbine to track the winds as they shift direction. A tail directs the rotor into the wind. In small-scale designs, the rotor is connected directly to the shaft of a permanent magnet alternator, which creates Alternating Current. This wild, three-phase electricity means that the voltage and frequency vary continuously with the wind speed. The AC output is used to either charge batteries or feed a grid-synchronous inverter, which turns it to steady, usable Direct Current. In small designs, the rotor is connected to the alternator, eliminating the need for gears. In larger systems, a gearbox is used to increase alternator speed from a slower turning rotor. A governing system limits the rotor rpm and generator output to protect the turbine from high winds. A shutdown mechanism is also useful to stop the machine during an extreme storm, or when you want to service the system. Understanding the Ratings Wind turbine rating is difficult because rated output is pegged to a particular wind speed, and different manufacturers compare different wind speeds to better promote their particular model. To understand the real power of wind, cube its speed. For example, 10 kph of wind, gives 10 x 10 x 10 = 1,000 watts. Or, a 10% increase in speed gives a 33% increase in power. This means that very small increases in wind speed create huge increases in power. This also means that a turbine that produces 1,000 watts at a wind speed of 28 mph, might produce only 125 watts at a wind speed of 14 mph - so half the wind produces 1/8 of the power. So ignore the rated peak output of a turbine, and look for the monthly (or annual) energy production you require (from your energy audit), estimated for the average wind speed at your site. After all, long-term energy is what you’re after, not peak output! If, for example, you know your home has 10 mph winds, and you need 400 KWH per month, you know what turbine to build. Knowing a turbine’s swept area may also help you calculate the annual energy output for the wind turbine. Jim Green at the National Renewable Energy Lab (NREL) developed a formula: annual energy output (AEO) in KWH = 0.01328 x rotor diameter (ft.) squared x average wind speed (mph) cubed. Easy!

Getting Started: Consider: Is it your aim to slash your bills, or to be completely independent? Are you going to be stand-alone, or will you still be connected to (and adding into/taking from) the grid? If you’re staying connected to the grid, will your local power company pay you for the electricity you generate?

First you need an energy audit of your home. Go to www.njcleanenergy.com for an accurate home energy audit, and great ideas on saving electricity and money. Sit down with your family, work out how many kilowatt-hours you all use, and find out where the waste is. But be realistic, reasonable, and think laterally. Just because you are now horrified at how much electricity your plasma TV uses, doesn’t mean the kids are never allowed to watch it. You may consider a smaller, more efficient TV for weekly use, and save the plasma for the weekend family movie.

Next, work out your location’s average wind speed, at a website like www.awea.org for the USA. When you know how much energy you need, and how much your wind will provide, you will be able to see the size of turbine you will need.

Now that you have a good idea of what you’re after, check out the DIY Wind Power Kits at EarthEnergyPlus.Com These kits have been selected with the DIY novice in mind, and include all the information you will need to build your own electricity-producing windmill! Detailed lists of the tools, parts, and where to get them. Video instructions you can play over and over. Great back-up from dedicated designers! Build your own wind power system this weekend, then sit back and watch your home-built wind generator turn a summer breeze into FREE electricity!

Home made windmill

Before all the crude oil will be used up to provide electricity for us, we might as well search for a renewable power resource. A very concrete example is wind power in which the wind generator can easily be installed at your home.

Switching to wind energy as power source is a more environment-friendly and cost-effective choice. A wind-powered house is advised to have solar panels as well for a more efficient combination.

Taking in these steps, you will be able to save the environment, spend little or none in the later part, and combat power outages.

What then are the things that you should consider if you are planning to place a wind generator at your own home?

First, your house should be on a big area. Wind power turbines work best when spread over an acre of land.

Second, check to make sure that the average wind speed in your area is 11 mph. If the winds in your area are intermittent, you can’t run the system efficiently. It is best if you consult an expert about the perfect wind power solution.

The wind turbine does not only produce energy but it has the power to draw water from the outside also.

The wind power generator is perfect if your house needs uninterrupted supply of power. As long as there is wind to turn the turbine, there is electricity.

A common wind power system consists of five blades and one tower. The length of the tower is dependent on your location. Towers need to be shorter when by the beach or loner if you are placed in a low wind zone. The power collected from the wind generator can even be saved for later use. So if you are into the savings and work efficiency, a wind power generator is best for you.
