Change With Renewable Energy
Change, hope, faith….
Words that presidential campaigns use to ride the wave of victory. What are these words, if not backed behind the people that believe them. We are headed down a path of destruction of our environment, of our future children and of ourselves. As a world we need to begin to take the next step to a better tomorrow.
What?
The green revolution.
Making tomorrow cleaner then today, is the goal so our planet will remain beautiful and perhaps even regain some of its past glory. The truth is that we as a race have been selfish. We take what we please from wherever we please with complete disregard for the consequences of our actions. Sure, a lot of the problems we caused were strictly naivety, but if that was just simply true, then why have we not corrected some of these actions ourselves?
What steps have we already taken?
Reduce, Reuse, Recycle – this mantra has began the reusing of materials to create new items. It is a step in the right direction, however it is needed on a much higher scale. Meaning that everyone anywhere should be responsible.
Researching alternative sources of energies. There are many alternative sources of energy
as you can see in advantages and disadvantages of renewable energy. The greater in-depth our research the faster these renewable energies will become viable. I suggest doing some of your own research into what are solar panels.
We have also began efforts in keeping our streets clean as well as regulations on emissions from factories and vehicles.
Whats needed?
We need to step up all of our efforts, and when we do this world will be better for it. Energy friendly appliances and conserving water, gas and any unclean energy we conserve and do not use unless we have to.
I hope my faith in renewable energies causes change.
Solar panels are a great way to help improve your home and a good start for green living.
Reasons Why You Should Go For Solar Power For Homes
Setting up Solar Power for Homes can be quite a challenge and costly, there are many considerations to be factored in, detailed designs to draw, and consultations to be made to
ensure that the right systems are installed and that ensure you get as much power in your house without spending too much money, time and effort.
However, most people today do not like discovering new things and exploring new alternatives because of over-reliance on the ‘system’. Here are some of the top benefits on why you need to make a wise decision today and invest in solar power for homes as your solution to power problems.
a) Solar power for homes are reliable and very cheap to maintain. This is primarily because solar panels have no moving parts and the only thing you will need to do is occasional cleaning and dusting and checking that all the wires are still in place. Once you have installed solar power for homes, you will not incur any additional costs such as repairs, if the systems are properly protected from human and animal interference.
b) One of the most important advantages of solar power for homes is that it is environmentally friendly, emit no carbon footprints and will not damage the environment that we live in. What could be better than knowing you are playing a part in ensuring that our children and their children that come in the future will find a cleaner and conserved environment?
c) Solar energy is a renewable source of energy, there is no time you can say the sun is dimmer because you are trapping lots of solar power for homes energy. You also need not worry about the sun every running out of its power because it is a star that has enough hydrogen to burn for billions of years to come. Solar energy is very reliable for use at home.
d) Enjoy flexibility and freedom even if you are living in a remote place or any environment you desire where it is not covered by the power mains. You can choose to install the power from the grid system just as a backup but if you install the right solar power for homes systems, you will not have to worry about running out of power. Of all the options of power to use at home, this is the most practical system to go for.
e) If you generate more solar power for homes than you need, do you know that you can sell the excess power to the power mains? This is a great opportunity for you to generate some income without having to worry about tedious work, the only thing you need is capital and do the installation of the system and you are set.
f) Solar power for homes have no stresses and no demanding maintenance on your part once installed. You will only need to clean the solar power panels and the storage batteries, you can kiss goodbye to hefty monthly electricity bills forever if you install solar power for homes.
Choices With Solar Energy For Homes
If you are exploring options with Solar energy for homes, you might look into passive and active heat systems. You also may wish to check out electrical generators. Active and
passive heating systems utilize heat from sunlight and transfer the heat to various parts of homes. Generators provide a free source of electricity for houses. Here are some of the options that you may wish to explore.
Active and Passive Heating
Passive solar heating systems are very simple in nature. For example, opening a window to let the sun in, can be a for of passive heating. This system can also be used to keep homes cooler, if incorporated into the landscape and structure design. Many homes are built with a great deal of southern exposure, to provide passive heating.
An active heat system utilizes a pump to provide heated water. Water is pumped into a collecting station, where the sun heats it. Heated water is then pumped to a form of radiant heat, that can be used in many houses. This system usually works best in warm climates.
You may see a lot of solar swimming pools with active heat systems. The pool pump pumps water to a collector, where it is heated. It is then placed into the water system of the pool. This system can save a great deal of the costs of standard pool heating methods, as their heat source is unlimited.
Passive heat systems can be very effective for heating hot water. They work in the same basic way that active pool heating systems work, except they do not utilize a pump. In order for this to work, they employ gravity, by being placed high above the plumbing system, on the roof.
Solar Generators
Solar generators can be simple or they can be complex in nature. Most of the time, these systems are used as a supplemental form of electricity for homes. It may not be cost effective to have systems that generate all of the power, although this can be done. These systems use a series of panels that make electricity from sunlight.
There is a wide selection of panel systems to choose from. The more efficient ones, tend to be more expensive, but they can be very effective. If you contact a solar energy professional in your area, he can provide a great deal of answers to your questions. You also can get an accurate estimation for installation costs.
Installation costs may be preventing some homeowners from installing these systems. However,
alternative energy systems can be an excellent investment in the future. If you plan to stay at your house for several years, you can recoup the investment, and enjoy free power.
Final Thoughts
When considering Solar energy for homes , you may wish to check into passive or active heating systems. The main difference between passive and active systems, is a pump for water. These systems are good for heating swimming pools and hot water systems. You may wish to have an alternative source of electricity, by installing solar panels on your roof. The costs may seem high, but once the initial investment is recouped, you may enjoy free alternative energy.
Basic Residential Solar Power For Everyone
Residential Solar Power makes it possible to become independent from the grid. It is also
a way of reducing the cost of electric bills. When we talk about electricity from the sun for home use, what comes into mind are photovoltaic cells and solar water heaters. While the heater is not a producer of electricity, the savings it creates by using sunlight to heat water can be substantial
A lot of us are getting used to photovoltaic panels mounted on rooftops especially in areas that get a lot of sunshine. Photovoltaic energy is becoming popular because there is already a lot of consciousness regarding the environmental effects on the conventional generation of electricity. Coal is the biggest type of fuel for most electric plants but the technology is highly pollutive.
It can be very expensive to connect to the grid in remote areas. In this setting it makes a lot of sense to invest in residential solar power. In cities and other places where the grid is accessible, the cost of generation using sunlight is more expensive than buying electricity from the grid. However we should take note that using sunlight as a means of generating electricity is becoming less expensive each day.
The silicon wafer is the heart of most residential photovoltaic power systems. These wafer are made in such a way to maximize the Photovoltaic Effect. Because each silicon cell only produces a small amount of direct current electricity, they have to be assembled in banks. For a solar power system to work, it requires two other components. The first one is the storage medium and the other is the inverter.
The purpose of the storage medium is to make electricity available especially at night. The most common type of storage device is the rechargeable battery. The storage battery only stores direct current electricity.
The other component is responsible for converting DC into a form that is usable by most home appliances. That component’s name is the inverter. An inverter is also a transformer because household appliances commonly work on 110 volts. The voltage stored in the battery is brought up to 110 volts.
A recent development in electric grid technology is the grid-tied system. When you are a producer of electricity you have the option of connecting to the grid. The other users of the grid will use some of the electricity you generated. At night, you get electricity from the grid instead of storage batteries. The best thing about this system is that if you make more electricity than what you consume, the grid will pay you for the surplus. Now that is great news.
While it is true that solar power is not new technology, it sort of stagnated because there was no economic incentive for it. For a long time coal and oil powered plants were so cheap to operate. Now with increasing cell efficiency and economies of scale, the difference in cost of producing your own electricity versus buying it from the grid is getting smaller. Now, isn’t it time you go solar?
Solar Energy Pros and Cons
Solar energy is steadily becoming more used both for homes and in the industry. We are
taking a closer look at what the potential and advantages of using energy from the sun, comparing them to the disadvantages.
Massive Potential
Solar energy is estimated to have a potential of over 7000 times what we need, available all over the earth. There is no doubt that the possibilities for harnessing this energy are interesting.
No Pollution or Emission
One of the biggest advantages with the use of solar energy is that there is no pollution or emission. This is crucial in our planets development towards more environmentally friendly energy solutions to fight the climate crisis
Several Different Uses
The most common way to use solar energy is through heating of a substance e.g. water. This heat energy can be used directly as heated water for e.g. a swimming pool or by a heat exchanger for increasing the temperature in your house. Solar cells have made it electrical generating possible.
In the recent years solar energy for homes has become more popular. There are good reasons for this, one of them being the increasing electricity and energy prices. Solar cells can be very low cost once the initial costs of construction and equipment has been taken care of. The same technology of solar panels can also be used for charging batteries of different devices. A 12 volt solar battery charger can be used for everything from cell phones to your car battery.
The climate crisis is getting worse. There is no doubt that we need all the help we can get from renewable energy sources such as solar energy. The problem with most of these sources is the economy. They are simply not competitive with e.g. oil and gas. We need to help these projects with incentives. Their potential is too
Criteria for Building a Passive House With Residential Solar Power
The passive house is a home that provides thermal comfort without the use of
“conventional” heating, ie the boiler and radiators, or similar systems. The energy needed to balance the heat of the building is typically provided with non-conventional systems (residential solar power or heat pump to heat the air of the energy recovery controlled ventilation).
The conventional heating system can be eliminated if the energy needed inside the house is very low, conventionally less than 5 kWh per square foot per year. These benefits are obtained with a very careful design, especially with regard to the sun, with the adoption of high-performance thermal insulation on outside walls, roof and glass walls and through the adoption of controlled ventilation systems for energy recovery and with solar panel installation.
Passive house has only three criteria:
- a frugal annual heating – cooling allowance of 4,733 BTU (British thermal unit, a traditional unit of energy equal to about 1,055 joules) per square foot
- an annual cap on primary energy of 11,1 kilowatt hours per square foot for all energy needs including heating and cooling, along with water heating, appliances, and other devices
- the building must be essentially airtight with 0.6 air changes per hour at 50 pascals of pressure.
Each benchmark is many times lower than the targets set by current U.S. energy codes and guidelines.
Passive houses are born in Sweden and are used mainly in Germany, Austria and the Netherlands and in other northern European countries. The first certified passive house project in the Unites States was actually an educational building. Completed in 2006 the BioHaus was designed by architect Stephen Tanner for the Concordia Language Villages campus in Bemidji, Minnesota.
The cost to build or get built a passive house made of wood can vary enormously. It depends on the type of construction required, the quality of materials and assembly. It depends also if you choice environmentally friendly products like Residential Solar Power.
Few Reasons I Love Solar Energy
Protection of the environment is everybody’s responsibility. We the present
stewards hold it in trust for future generations. So that, whatever we do today will affect our children and their children. Development and economic growth have environmental implications. And under our watch, it is important that we adopt ways that will help protect our environment from bad and harmful elements. One way to contribute to environment protection is to be conscious with how the electricity being used is generated.
Energy-related activities are among the top pollutants of our surroundings. Oil and coal fed power generators emit carbon that contributes to global warming. On a personal level, one can help reduce carbon emission by using clean source of energy such as solar. It is an energy derived from sunlight, a very natural source. An environmental advantage of solar energy is, it does not emit materials harmful to living things and the surroundings. There are solar technologies fit for individual homes that are now available in the market.
Other advantages of solar energy are, it is renewable, its capture for electricity use can be done individually without need of facility and bulky equipment, and it reduces electricity bill. Being renewable and sourced from sunlight, it will be available as long as the sun shines. Unlike fossil oil, it is renewable on a regular basis and exists over an indefinite period of time. And now with the help of technological innovations, solar can be easily captured through the use of solar panels. Solar panels are made up of cells that covert sunlight into electricity. For houses that are not connected to the grid, solar energy could be a better option. Another advantage of Solar energy is it reduces bill because sunlight is a free commodity. And in some countries, there is a system where one can even sell the extra electricity generated from solar.
Starting Small and Going Green
Despite what major advertising would like you to believe, going green does not mean buying a hybrid. A green lifestyle does not require that consumers buy
recycled plastic. For that matter, a green lifestyle does not necessarily involve a garden, low-flow appliances, or even diy solar panels. Although these things really are positive steps forward, environmental awareness begins one small change at a time – starting with our very own habits.
Sure, riding the bus may not seem as attractive as going out and buying that new gasoline efficient vehicle, but nobody ever said that living the eco-friendly life was going to be glamorous! There are plenty of ways to use what we currently have to achieve the green dream. For instance, one easy change is to drive less and drive slower – every ten miles per hour over sixty is comparable to adding fifty cents to the price of each gallon of gas.
Replacing major fixtures with water-efficient varieties may not be an economical option for many environmentalists – but everybody can take the initiative to shut off the water while brushing to save up to five gallons a day. Keeping with the topic of water, you may be interested to know that daily showers do nothing to increase health and a proper diet will balance bodily oils to make sure that nobody finds out you skipped!
Going green also requires honing the art of avoidance. Practicing restraint when buying new products is half the battle – finding ways to reuse household junk is the other half. In many cases, the principal of “reduce and reuse” can eliminate many recurring purchases.
Small steps like these will ease the transition to a more sustainable future. Going green starts with you, and your actions can help to influence a whole new generation of responsible, environmentally-minded individuals! Using DIY solar panles is a great start.
Rechargeable Solar Batteries
Solar Batteries are yet another way people are saving some money and helping the
environment at the same. They do not need any electrical source to charge as they only use the sun. They maintain their own rechargeable batteries and can be used for your camera, ipod, cell phone, laptop, hearing aids and car battery along with most other commonly used equipment. Solar battery chargers work by collecting the suns rays through a PV solar panel and then transforming the energy into electricity and storing it in batteries.
There is quite a long list of advantages to using renewable forms of energy but we will just look at a few of the benefits of solar power here.
Though coal is a cheap way to generate electricity, it also contributes greatly to the sulfur dioxide in our air as well as to mercury pollution. In contrast, solar energy is very environmentally friendly and does not generate emissions, wastes or byproducts at all. Not to mention, the energy we get from the sun is completely free!
Considering that you can find sun pretty much anywhere in the world (during the day time anyway) a solar battery charger could be a great emergency back up. Most of us have had batteries die at some point when we really needed them and there was no electricity in sight. These work even on cloudy days though it will take it longer to charge.
Solar battery chargers come in many different styles and sizes. Most can be found in 6 and 12volt versions with 5, 10 or 20-watt power film solar panels. These can fold up, don’t weigh much and are great for outdoor activities. There are even DIY instructions that can be found for free on the Internet along with DIY solar panels for home but with so many on the market now it may not be worth your investment of time.
