Clean And Lean: Why Green Energy Is Such A Hot Topic

A lot of people are concerned about the environment, but don’t have a good idea of what they can do to help. Interestingly, an environmentally friendly energy industry has been emerging to serve customers who are interested in making a difference. This article provides many tips so you can live a green lifestyle.

Be sure to check the insulation levels in the areas around your house. Insulation helps keep the warm air out in the summer months and the cold air out in the winter months. Places that you should check include your attic, crawl spaces, all exterior and basement walls, ceilings and floors.

Remember that solar panels, whether you install them on your roof or anywhere else on your property, must be angled toward the sun to receive maximum exposure. In the Northern Hemisphere, this means facing them south with an angle of latitude plus fifteen degrees. Otherwise, your investment will not return as much energy as you hope.

Try heating water using solar power to further implement solar power into your needs. For many people, solar power is still a thing of the future, but it doesn’t have to be. There are many ways to include it in today’s world, and using a solar power for all your water heating needs is one of them. Think about how much your current water heater is used, and think about how much money you could save.

Use light bulbs that are energy-efficient. Conventional light bulbs use entirely too much energy and create a lot of heat. Energy-efficient bulbs last much longer and don’t give off that much heat. They can sometimes give off dimmer light, so make sure to use as many as you need in your rooms so you have comparable amounts of light.

Contact your local utility company to see if purchasing energy from renewable sources is an option for you. Buying green energy directly from a power company is one of the easiest ways to go green with your energy use, without having to invest in any major alterations to your home.

When shopping for appliances, computers or other electronic items, look for products that wear an Energy Star badge. To earn the right to display the Energy Star logo, products must meet certain energy-efficiency criteria. There are different tiers of efficiency as well, which can translate into additional energy savings over the lifetime of the product.

You can save a lot of energy simply by investing in a tube of caulk and walking around the interior and exterior of your home, sealing any visible cracks or holes. Windy days are the best time to seek out less visible leaks, as you are more likely to hear or feel them.

Save energy, and your hard-earned dollars, by only using your washing machine and dishwasher when you have a full load. A small load uses just as much energy as a full load and accomplishes a lot less for the energy expenditure. Let laundry stack up another day or two in order to maximize savings and efficiency. Also consider drying clothes outdoors on a clothesline if allowed in your area. The fresh outdoorsy scent can’t be beat, and you will show a significant savings in your utility bill if you cut back on your dryer usage.

If you are thinking about starting your own business, you should find out more about green energies. This market will expand in the future and you can benefit from many interesting tax incentives, besides contributing to saving the planet and offering people clean sources of energy. Go to your local Business Bureau for more information.

Swap your old incandescent light bulbs for high-efficiency LED or compact fluorescent light bulbs. These bulbs use far less electricity than incandescent, and they come in sizes that fit most existing fixtures. While the up-front cost is generally higher, most of these bulbs will last for years before burning out.

As was mentioned at the start of this article, green energy has garnered quite a bit of interest in the media and amongst everyday people. Sadly, some people aren’t sure how they can implement green changes to live a more sustainable life. This article provided suggestions for environmentally concerned and compassionate people.

A Look At Green Energy Solar Powered Homes

Solar energy is a form of power that is clearly derived from sunlight. Solar power can be utilized in a wide variety of applications. Through architectural techniques, it can be used to heat a home. Through more conventional panel applications, it can be used to power a car. Further, people can utilize the sun to purify water that would be otherwise unfit for humans to drink. Each of these takes on solar power will be discussed in this article.

One interesting advantage of using solar energy is being able to sell power back to your local utility power company. Many of the utility power companies have programs where they will buy excess energy generated by your solar panels. The way it usually works is a device is installed in your home which measures the excess energy generated, after your home energy usage. The amount of excess energy is siphoned off and purchased by the utility power company.

Another thing that you should do is ensure that your walls and attic are properly insulated. If you are cooling your home and you do not have the right insulation, then a lot of the air that you are cooling is being wasted. Just by ensuring that you have the proper insulation in your home will help you save a lot of money and help you get the most out of the energy that you harness from the sun.

Next, you will need to decide how big of a system you need. This is dependent on how big your house is and how much energy you consume. You can look on your electric bills to determine your energy needs.

One cost saving option is to purchase solar energy panel kits and do it yourself. From adding solar panels for a solar energy water heater to full roof conversions, many of these options are widely available. In the case of solar panel installation, keep in mind to check with local and state government for regulations. Also, remember to check with your home owners association for any rules they might have regarding outside solar panels.

Solar powered items available on the market become more and more plentiful by the day. If you aren’t ready to install a complete solar system in your home yet, you can begin collecting individual solar items such as lighting, radios, heaters, flashlights, vehicle ventilators, calculators, mosquito inhibitors, outdoor lighting, pool purifiers, fountain pumps and more.

For around $50, you can stop charging your phone at work to slow the drain on your electric bill. Chargers for all the small devices consumers now use have come under fire recently for drawing power even when the device is charged or not plugged in. Instead, these solar powered battery packs will charge just about any rechargeable device without using your home’s power. All you need to do is leave the solar cell in a sunny window for a few hours and you’ll have a free charge for your phone. The most common interface for these devices is a USB, but you can also get ones that will charge specific models of phones, or even your AA’s.

Solar power is the wave of the future. There’s no reason you can’t get on top of that wave right now! Being in that position already offers solar-minded homeowners some great potential savings, and the situation will only improve as time goes on. Take a look at your home from a fresh perspective and see if you can’t find a way to make the sun work for it.

Building solar panels for your home is not as difficult as you think. And it is quite affordable, too. To help you get started visit these very informative Solar Energy Sites – Installing Solar Panels on Your House, Benefits of Using Solar Energy.

Save Big On Your Home’s Solar Power System

All around the world people are being hit with rapidly increasing costs of living. For some, this making it ever harder to make ends meet and any way to cut down on the monthly and yearly outgoings is welcomed with open arms. One area that many people are looking at is the investment in renewable energy sources such as solar panels and solar heating.

Find a solar power professional and have him or her inspect your property to determine whether or not solar energy is a good option for you. A solar energy system will work best if you have enough room for a certain number of panels and if your property is well-exposed to sunlight. If you live in an area where the sky is usually overcast, solar energy is not a good option. Solar panels function best in the South-West of the U.S. and in extremely sunny areas in general. If you do not live in a sunny state, you should look into other green energy systems.

You can use solar energy to heat your home in many ways. You can use solar panels to do this and run a electric furnace or heater or you can also use passive solar power to heat certain elements in the construction of your home to release the heat.

Solar panels are really an amazing thing. You’re not dealing with anything like a magnifying glass burning an ant through the sun’s awesome power. What you’re looking at with solar panels is the absorption of the sun’s UV rays, its energy. This stored energy is then converted to usable energy for your home appliances. Obviously, as science progresses, solar panels are going to become more efficient. But even as they stand now, you’re watching a really cool event happen. The sun’s rays are being converted into the type of energy necessary to watch TV and run your AC.

Instead of using conventional powered lights to decorate your lanai or patio, you can incorporate solar light on the outside of your home. This can really make you home look great and it will help you save a little bit of cash each month on your electric bill. These little lights are armed with small solar panels and batteries which harness and store the power of the sun throughout the daylight hours. During the night they light up in the absence of sunlight and utilize the stored energy to shine all night long. This is a relatively inexpensive way to begin to utilize solar power in your home.

What are the environmental benefits? Unlike traditional generators, solar panels do not release any carbon dioxide or other pollutants into the atmosphere in order to produce electricity. A 3kWp solar PV system can, on average, save over 30 tons of CO2 from being released into the atmosphere during its lifetime.

Another thing that you need to know is that during the night you are producing no energy. This means that you will not be able to run any electrical items unless you invest in a large battery that can store the solar energy during the day. This makes solar energy even more costly.

Although this general outline doesn’t get into the nitty-gritty details of solar panel installation, you’ll find that the process really doesn’t get that complex. Deciding to take the plunge is by far the toughest part of the job. If you’ve read this far, you may be on your way to buying some solar panels of your own. Keep educating yourself on the topic, and you’ll have all the information you need to make the right choice.

How Solar Energy Works Best For Your Home

The Sun is the star of our galaxy and its rays provide us with all the energy we will ever need. Even so, because of the distance between Earth and the Sun, coupled with the effects of clouds and our atmosphere, very little of the energy that began the journey reaches us.

By the time sunlight arrives on the earth’s surface, it is composed of 49 percent visible light, 45 percent infrared radiation, plus lesser amounts of ultraviolet and other types of radiation. Most people who are unaware of the science, assume that we harness the light element of sunlight, but that is not so. It is the radiation that can be converted into electrical energy or – which is the easier route – into heat (thermal energy).

The science of solar power is in a very early stage. If only we had better technology, we could use sunlight for all of the planet’s energy requirements. The advantages of this are easy to see: it is a never-ending supply (for the next million or more years, at least) and is totally pollution-free, unlike the rapidly disappearing supply of fossil fuels we currently rely on.

Solar energy is relatively cheap. It’s free at source and the costs of harnessing it – although high at the moment – are coming down all the time. Most people just do not realize how vast the potential is. Every single day, 200,000 (that’s two hundred thousand) times the electricity we generate on earth in a day, arrives in the shape of solar power.

Solar panels are called “collectors” in the trade, and their job is to collect solar energy and to convert it into thermal energy, or heat. There are two overall types of solar collectors, known as concentrating collectors and the more common flat-plate collectors. Because of the low concentration of sunlight reaching the earth’s surface, both need large areas of panelling in order to collect the radiation needed. A single person would need something like forty square meters, even in a sunny location such as California, Arizona, Sri Lanka, Italy or Greece.

Simple flat-plate collectors are made up of a blackened metal plate, covered with sheets of glass. The sunlight falls on the panel and the heat is trapped. Tubes at the rear of the device hold what are known as “carrying fluids” – usually water treated with antifreeze -and that will take the heat to an insulated boiler or other collection and storage device.

“Solar furnaces” are used when a much higher temperature is needed. Also known as “concentrators”, they collect sunlight over a much larger area and focus it using mirrors and lenses. The temperatures can get as high as 3,600 degrees fahrenheit (2,000 centigrade) and normally they’ll make steam to be used in engines for electrical generation.

We will probably be more used to seeing the third type of solar device, which are called photovoltaic – or solar – cells. The cells work when light hits a junction of a semiconductor and a metal, generating a small electric voltage of roughly two watts. These are what you find on solar-powered calculators, radios and wristwatches. If you need to generate thousands of kilowatts of electricity, you have to connect hundreds and hundreds of cells together to make what is known as a solar electric plant. Because the energy efficiency of current photovoltaic cells is less than 20%, the scientists are hard at work, hoping to increase this efficiency to make solar cells viable as viable generating units.

Because of this, solar energy is called a renewable energy source. As long as you live in an area that gets sufficient sunshine you can save thousands of dollars a year on your energy bills, while reducing the amount of pollution put into the environment a good deal. Finally, the more people that invest in solar panels, the cheaper and cheaper the panels will get, enabling even more people to join in with you and buy solar panels as well.

Ask your realtor whether they will receive more money by selling you a solar-powered home if you are being encouraged to purchase such a home. In some states businesses offer realtors incentives for steering customers towards solar-powered homes and in others realtors can get an increased commission for selling a solar-powered home.

Some people are afraid to install solar systems in their home because they may not have power on a cloudy day. However, solar system do still work on cloudy, rainy days. The power will just be at a reduced level.

Solar system is low maintenance. These systems require little to no maintenance, further reducing the monthly drain on your cash flow. About the only chore you have as the proud homeowner, is keeping the panels clean. Professional upkeep is minimal and infrequent.

As you may have already begun to understand, the decision to retrofit your home with solar energy panels is filled with subtle nuance. Depending on your individual circumstances, it may benefit you greatly, or you may struggle to break even on your initial investment. Whatever the case may be in your individual situation, making an informed decision is always better than leaping in head first and hoping the it all works out.

Like you, your solar collectors are made up of small pieces called cells. Unlike you, all of these pieces serve the same function. Each one generates a small amount of power. You could get the same effect by wiring hundreds of AA batteries together, although it wouldn’t last very long. These cells actually work very similar to batteries. Each cell has a positive and negative side and power is generated by transferring electrons from the positive side to the negative. Once this transfer occurs, the electrons will naturally move through the wiring of your home back to the positive side, which is what makes up the electricity you use every day. The reason that batteries wear out is that they use a chemical reaction to produce this movement of electrons. Once the chemicals are used up, there is no way to create a reaction to move electrons. Solar cells use energy from the sun to make that transfer, and sunlight isn’t about to run out anytime soon.

Try and consume less energy on a regular basis. You do not want to consume more than you should be consuming because this can make you waste all of the built up energy your home has stored. You want to be conscious of this especially in the colder months of the year when there is not as much sun. Although the sun rays penetrate the clouds that cause gloom, they do not provide as much energy to your solar panels as they would get during the sunnier days out of the year.

With the clean energy awareness level at an all time high, solar energy is one of the most attractive alternate energy options. Solar energy is a clean alternate energy option which is good for the environment. These days, solar energy is considered one of the most green energy alternatives.

Clearly, there are a few drawbacks to installing solar cells on your home. However, there are many benefits that make solar panels a economical long term investment that pays off in the long run.
