Wind Power As An Energy Source
Renewable energy sources are infinite, clean and affordable. Wind power is a major source of renewables that is continuously growing worldwide. So as to meet the high demand for alternative sources of energy, wind energy equipment and generators have been deployed in wind farms to harness this clean energy source. More so, home owners have adopted home wind power generators that are practical and efficient in electricity production.
For hundreds of years, old Holland has used the wind’s energy to grind grains and pump water. Today, a modern equivalent, the wind turbine, converts the wind energy into electricity.
Wind turbines are usually a familiar sight in most countries around the world, but do you understand how they actually work?
How It Works
Wind turbines, like the windmills, are setup on a tower to capture the wind’s energy. At the height of 30 meters above the ground or more, the turbines take advantage of fast wind with less turbulence. The turbines harness wind energy by utilizing their propeller blades. The 2-3 blades are placed on a shaft to set up the rotor system.
The turbine blades use a similar mechanism as airplane wings. When the wind blows near the surface of the blade, a low-pressure pocket forms on its base pulling the blade in its direction making the rotor to rotate. This movement is referred as a lift. The lift force is powerful than the drag force on the blade’s front. Combination of the drag and lift makes the rotor spin in a propeller motion. The turning shaft is connected to a generator that generates electricity. Wind turbines may be connected to a utility power grid system or used in stand alone applications. For large scale purposes, some wind turbines are utilized to create a wind plant.
Advantages of Wind Power
Since wind power is the among the fastest growing alternative sources of energy, it extends many benefits. No matter how much we use it at the present time, this renewable and free resource of energy will still be present in the future. The energy actually stems from nuclear fusion that occurs in the sun. Unlike the conventional power plants, wind power plants do not emit greenhouse gases or air pollutants. Moreover, large scale use of wind power creates energy independence from other conventional sources of energy.
Wind power is the lowest priced alternative energy technology available today. It only costs 4-6 cents for a kilowatt-hour. Thanks to the continual technological advancements, prices are expected to decrease due to demand in the future.
The potential of wind energy is unlimited. Harnessing may be done in almost any location. Additionally, wind power has the capacity of growing immensely. Although wind energy accounts for only 2.5% of electricity supply and production, it can grow up to 25% every year.
Operational costs involved in wind power generation are meager. However different turbines may necessitate different maintenance operations than others. Whats more, residential wind power gives homeowners the opportunity to save money and be free from power outages. Wind power provides good domestic potential as people may generate electricity the same way they do with solar energy
Disadvantages of Wind Power
Although the costs for wind power may appear significantly small, the technology begs for high initial investment compared to fossil geared generators. Due to this, wind power has little chance against the strong competition from the well-established sources such as coal.
The primary challenge facing wind power is its nature of being intermittent. It cannot address energy demand unless a storage method is used. It becomes difficult to harness the wind as their timing may interlock with electricity demands. Wind resource investment is a large development that necessitates a lot of space. It may compete with other land uses that may be lucrative than the generation of electricity. People that surround wind power plants report noise pollution as an issue that affects them.
Wind turbines may at times be a threat to wild animals such as birds and bats. When flying creatures hit the blades of a rotating turbine, the chances of them surviving are slim to none.
Regardless of these disadvantages, the future of wind energy is promising. The development of massive wind farms is taking place to boost the clean and efficient energy resource. Nations that are at the forefront of developing this renewable energy source include China, Germany, Spain, India, United Kingdom, United States of America and Canada.Read More
Greenhouse Gas Emmisions
Greenhouse gas emission is one of the most destructive occurrences that seem to be causing global warming. Greenhouse gas emission tends to trap the heat from those gasses into the planet and makes it warmer with time, this in brief terms, is explained as global warming.
Humans are rationalizing the activities that are increasing the amount of greenhouse gas emission each day. We burn fossil fuels that emit the dangerous gasses, buy cars and use motor vehicles that emit CO2, everyday electricity and heat generating rituals that seem to damage the environment.
The compounds found in the dangerous gasses trap the heat into the atmosphere causing the earth’s surface to become warmer day by day. This causes the greenhouse effect of climate change yet known as Global warming and is damaging the ozone layer. The deadly gasses that are known to be notorious for the earth’s surface include:
CO2 (Carbon dioxide) – the gas emission by human led activities that is produced in abundance in the result of deforestation
CH4 (Methane) – the gas that is released by fertilizers used for agricultural process
N2O (Nitrous oxide) – the gas is released from burning of fossil fuels and industrialization
Fluorinated gasses – the three main fluorinated gasses include (HFCs) hydrofluorocarbons, (PFCs) perfluorocarbons and (SF6) Sulphur hexafluoride. The main sources of these green glasses are the industrial process and electric appliances used at home.
The strong gasses fail to react to air pressure and temperature change occurring in the atmosphere of the earth as they are well mixed into the air. They are stubborn gasses that are present in the atmosphere for long period of time and thus aren’t easily removed from the earth’s atmosphere.
Global warming thus affects the atmospheric circulation adversely by changing the weather and even climate patterns in the various regions of the earth. The rain patterns change in a way that warm regions of the earth are getting colder whereas the cold regions are getting warmer.
The damaged caused to the ozone layer is causing the polar ice caps to melt and thus sea levels in the northern region of the earth are rising hazardously. The adverse effects of the greenhouse gas emission have already begun and we fail to recognize the threat it has posed to the earth’s atmosphere and has already caused the extinction of marine creatures and other mammals.
The CO2 coming from man-made sources are comparatively smaller than natural emission of the gas but regardless of its little amount, it still tends to upset the natural balance. The carbon cycle existed in the atmosphere long before the Industrial Revolution came into being.
The danger lurking in the atmosphere by the green gas emission comes from both natural and man-made progression but it’s the human activity that has led it to offset from the natural balance. If it is the manmade progression that is causing the earth irreversible damage then the responsibility of its eradication is also up to us. We can help the earth, which is the only planet humans can survive on, by doing more than just planting trees in abundance.Read More
The world has grown into a place of immense pollution. The need for green living is more than ever now. Putting fines carbon emission coming from vehicles, building our homes from decomposable materials seems to be seldom. Green architecture is one of the most sustainable methods to keep the negative impact of building materials on the surrounding environment. The concept of green architecture is consolidating the building with greenhouse materials in different designs that make them environmental friendly instead of using man-made concrete that proves to be harmful to the environment.
Some green building materials used for green architecture are:
Straw Bales- these were used to create firm wall frames instead of materials like concrete, wood, plaster etc. they can still be used to build the structure. They prove to be beneficial for the environment and are successful in providing insulation from hot and cold climates, they are also affordable and are renewable too.
Rammed earth- tamped dirt down gives a similar feel of concrete yet it is more natural. Dirt tamped down firmly in a wood mold, and can be structured by using rebar and bamboo; it is a modern technique of the ancient times that is equally eco-friendly.
Wood- wood is the world’s favorite material to bring out the modern yet typically classic representation of one’s homes. The use of wood never got out of fashion with time and the fact that it comes under eco-friendly building material that doesn’t require much energy to process into building materials.
Bamboo- this material is still popularly used in some parts of the world and that is because of its ductile strength. It is light weight and renewable resource to create building frames that can be used in low-income areas or eco-friendly led areas.
All of these materials are low-cost, renewable resources and eco-friendly materials that are safe to use and require less energy consumption. Any material, which is considered eco-friendly, comes under the basic criteria of the product being- efficiently resourceful, provide better air quality indoors, efficient energy and water consumption and affordable raw materials.
These green building materials are obtained from recycled content, are locally available in plenty by nature. The concept of green building and green architecture proves to be better for the environment and helpful for waste management techniques. The concept proves to be conducted by erosion of soil, harvesting the materials with the use of rainwater and solar energy used to conduct solidification thus the use of non-renewable energy is substituted by renewable resources.
This means using green building materials comparatively uses less of man-made energy, better-allocated use of water than what is used in concrete and other non-renewable materials. Commercial concrete releases carbon dioxide into the atmosphere which is harmful to the ozone layer – the reason why countryside of a State seems to have healthier air than the air you feel in the city with skyscrapers. The dangerous emission of the gas that damages the environment is already beyond control because it’s the man-made material which releases these gasses that damage the nature.Read More
Teaching Our Children About Renewable Energy
Teaching our kids to save energy can be a lifetime value that they can use in their life, and be passing that knowledge to their kids when they’ll have a family of their own. It’s also efficient and effective to teach kids new things when they are still young because they can easily learn them. But as much as possible, make it fun to learn. So here’s a list in teaching your kids on how to save energy in a fun and exciting way:
- Educate and reinforce
Kids learn so much at school. And as a parent, you should ensure that they do not stop learning at home. To encourage your kids to learn about clean energy, you should educate them and make sure to reinforce what they have learned. You can discuss to them the energy sources of your appliances and why conserving energy is important. You can also ask your kids to write down rules at home about saving energy and every time they follow those rules, they will get a reward at the end of the week. Additionally, let them identify if you are wasting energy or not.
- Build a garden and grow some plants
Growing some plants in your backyard will give your kids more responsibility and this way, they can learn how plants can help the environment. Children also love to make new things and they take pride in their own creation.
- Go out and have fun
Take some time going out with your kids and challenge them to take a few hours per day to get off their gadgets or just plainly to keep every appliance off. You can take an adventure to the beach, or have a picnic in the park, or explore the neighborhood using a bike. This way, you can strengthen that family’s bond and you show your kids that it’s more fun and exciting outside.
- Allow them to redesign their own energy-efficient room
Kids love to take charge of something. By letting them redesign their own energy-efficient room, you allow them to be involved in the process and this way, you can ask them what the possible things they can have for their room that will conserve energy. By this, you teach them to be energy-efficient.
- Conserve together
You should also follow the things that you have been teaching to your kids. This way, you do not just save the environment but also your family’s monthly bill. And because you saved so much on your bill, you can let your kids choose what the saved money should be spent for. The more the family saves money, the more you can have fun.
- Teach your kids these habits:
- Turn off the lights and all other appliances when leaving the room
- Close the doors and windows after going in or going out when running heat or air conditioning
- Do not leave the fridge door open
- Take a short shower instead of long baths
- Avoid repetitive and unnecessary opening of the fridge
- As much as possible, use daylight to lighten up the room
- Turn off the water while brushing your teeth
- Do not play with the light’s switch
Why Every Home Benefits From Energy Star Windows And Doors
The type of glass windows and doors installed in a home plays a huge role in regulating energy. The ones that are efficiently designed functions well in both hot or cold climates. Luckily, Energy Star-qualified glass doors and windows have been introduced in the market, helping homeowners benefit from the efficient use of energy notwithstanding the climate in their region.
What makes Energy Star qualified windows and doors distinct from the rest?
Apart from carrying the Energy Star logo, these windows and doors are set apart from the others in the market because of their special features.
Effectively designed to manage heat
Traditional glass doors and windows are made of single glass panes. This feature instantly allows heat conduction in and out of a home or office. In addition, typical window frames allow heat to escape easily if they are constructed out of aluminum which is known for its high heat conductivity. On the other hand, energy star qualified doors and windows are made of special multiple glass panes. They are designed to have air spaces between the glass panes, allowing minimal heat transfer. Heat transfer is further minimized when harmless gasses are incorporated between the panes. Krypton and argon are typical types of gas used for this purpose.
Offer savings on utility costs
Clients who have had these products installed in their homes attest to savings of around 12 percent on annual utility costs. You can find these products in just about any store that sells doors and windows. You can also ask your local window cleaning company their recommendations since they work with windows all day.
This offers valuable savings especially if accumulated over time. The amount saved can go even higher (up to 30% on heating and cooling costs) depending on the windows replaced and the climate type in the area.
Keeps noise pollution at bay
Energy star windows and doors keep unwanted noise out of the home. If you are one of those city dwellers who happen to be in a busy, high-traffic area, near train stations, or close to neighbors with noisy rowdy dogs, these products are a boon for you for they keep these “annoyances” out of your home. You get the rest and sleep you need without being disturbed.
Regulates heat and light energy
These special windows and doors carry low emissivity coatings. This allows heat to penetrate your home during winter time or to escape during summer time when the heat can be quite extreme in some regions.
In some areas characterized by northern climates, heating inside the home is very much desired. These glass windows and doors allow the full range of light into the home. Heat energy isn’t allowed to escape out because of the multiple pane and minimal U-factor. It retains heat similar to that achieved by the greenhouse effect.
For areas generally experiencing the hot southern climate, Energy Star windows and doors also effectively keep warm air out
Windows and doors that are truly energy efficient will result in yearly savings on cooling and heating bills. Select the right glass doors and windows, ensuring that they are Energy Star qualified.Read More
Efficient Energy Sources
Primary sources of energy are in forms of nuclear energy, natural gas, fossil, thermal, hydro power etc. which are transformed into a secondary energy source that is electricity. The renewable sources wind and solar energy and non-renewable sources like coal, oil and natural gas help in generating electricity. Before using these energy sources to generate the power we need to calculate the cost of the whole operation, the capacity of the factors we are using and the effects it has on the environment.
An efficient energy source is one that provides the electrical energy we need and where the cost, the capacity of the factors used and the adverse effects on the environment are minimized. This will generate efficient electricity that will cut the costs on electricity bills while reducing carbon pollution. Following are a number of power generating techniques that are cost efficient, renewable and eco-friendly thus with the efficient allocation of energy can be done.
The energy coming from the tidal stream and can help in generating power. The tidal stream can generate eco-friendly electrical energy which is easily predictable as the earth and moon motion system. The tidal power system can generate enough electricity to provide to homes and offices.
Using the sun as a source of generating power has been widely used all around the world to run environmentally friendly operations that require electrical energy. Modern technologies readily use solar energy to generate enough power for running their operations. Solar cells are efficient to generate electricity as they are easily transportable and very flexible. The modern technologies have been using renewable solar power to run small scale successful inventions like vehicles that run on solar power and the solar powered printer. If we talk about large-scale energy consumers there are towns that are run on solar energy, artificial satellites also consume solar energy to operate. Countries like China and India are building energy efficient building and offices that run from solar energy.
Wind power uses wind energy by way of wind turbines to generate electricity or mechanical energy. The energy sources of Large-scale wind farms are the local power transmission networks that provide electricity to isolated areas. As per the size of the units, they are capable of powering large appliances and even entire houses with power generated from wind energy.
Hydroelectricity is generated by the production of power through the gravitational effect of water that is fast flowing or falling. The renewable, most efficient and eco-friendly source of energy is consumed by a complex power plant. It is the second most used source of energy to generate electricity after solar energy.
