An energy source that is cheap and never-ending. Ideal, isn’t it? Who’d not want such in their doorsteps? Definitely not me. Perhaps you can say the same thing about you either. Not only would you be able to save hundreds and thousands of dollars annually from electricity bill, you’d even help the environment by having one more head not dependent on fossil fuels.
Many nations have already seen their advantage. Many among those have already started maximizing the potential of these renewable energy sources. Your community may not have started yet with the harnessing of natural energy source, but don’t let this stop you. You, yourself could already start in your own home.
For residential areas, one of the easiest and best renewable energy source would be solar energy. Especially among those places where there is an abundant sunlight, this is a good way to generate electricity for your household. There are many ways to harness solar energy, but the most common one is through solar panels. Solar panels may be perceived as expensive due to its rarity and not being readily available to the market. But if you are going to calculate its long-term cost and effect, you will realize that you are investing for a long-term and much bigger savings.
So how do this work?
You can outsource for reliable solar panels. You may not be able to buy this at your local Home Depot, but you can scout the internet for them. The Internet is a good source of information so one way or another, you can find a company that is able to give you the panels you need. You can situate them into a strategic position where they can be directly hit by the sun’s rays. It could be a garden, a lawn, or even the roof. You can also consider attaching these to your garage doors if it is a place in your house that receives the most sunlight. You can check out with your garage door specialists on the probability of this, and buy garage parts online if they can help you attach these panels to your doors.
Take note that if you are going to choose the roof to put your panels, solar roofs are already available. These function the same way as solar panels the way they process the harnessed energy and transform them into electricity that can power the appliances in a household. The only difference is that the panels here are already integrated into the shingles of the roof.
It is important to seek the assistance of professionals for fixing the wiring of your solar panels to be able to integrate it properly with your current at home. If this is not properly synced, your solar power may not work. Ensure also that the number of solar panels you have is capable of supplying the power needed by the appliances you have. All of this information can be supplied by your technicians.
There is no doubt that renewable energy source is the best way to save and to help the environment today. Let’s all start saving. Give solar power a chance today and generate more savings for your household in the future.
The effects of climate change are much more felt at this point. This is why it is vital to invest in infrastructure for renewable energy sources.
One of the best sources of energy is wind power. The BBC reports that wind is created by the giant convection currents in our atmosphere which is produced due to the heat that is released by the sun. Wind is clean energy as opposed to coal and gas which are unsustainable energy sources and have harmful effects to the environment.
A typical car running on gasoline releases at least 20 pounds of carbon dioxide per one gallon of gas. This means that it can actually emit about six tons of carbon per year. Now, what if a car needs exhaust repair in Phoenix? How much more carbon dioxide it emits, right?
This example underlies the need to look for renewable energy sources such as wind power. Here are the reasons why this energy source is sustainable and earth-friendly:
1. Wind energy is naturally replenished.
As long as the sun is shining, there will always be wind energy that can be generated. This means that this type of energy is renewable and clean.
2. Wind energy is eco-friendly.
This type of energy does not release greenhouse gases and does not pollute the land, water and air. This is why this is referred to as green energy. With wind energy also comes the reduction of overdependence on oil and coal and even fossil fuels.
3. Wind energy is cheap.
While the installation itself of wind turbines may be expensive in itself, this is nothing compared to the costs required in drilling for oil and gas and fossil fuels. At the same time, the cost for the construction of these wind turbines are also offset by the very low operational costs. There is virtually zero to minimal maintenance required in the maintenance of wind turbines.
4. Wind energy does not take up much space.
You do not need a lot of land to build a facility of wind turbines. A large turbine can in fact already provide for the needs of 600 homes. Turbines can even be built on land that can serve various purposes. For example, a turbine can be built on a farm land or an agricultural land and it will not affect the land. Some countries even offer tax breaks on the installation of wind turbines and other renewable energy sources which are definitely helpful.
5. Wind energy can help local economies.
With the installation of wind turbines in rural areas, the cost of electricity is lowered and people tend to benefit as businesses boom, more economic opportunities open up, among others. Some countries with individual citizens or cooperatives owning wind turbines even allow them to sell their excess electricity to private companies, adding to their income. Also, the presence of wind turbines can create more jobs for community members. In fact, research shows that wind energy may bring 66 percent more jobs compared to unsustainable power sources.
Renewable Energy is the hottest trend at present. Not only does it provide an alternative source of power without the presence of expensive cost, it is also abundant in nature. One could just install solar panels on their garage doors to harness solar energy, and transform it into the power that could be used to light the household. Very accessible and easy. Not to mention, cheaper in a long run.
One of the main barriers prevailing renewable energy technologies introduction in Bangladesh is the information barrier. Decision makers, educational institutions and local companies have so far little or no access to information about Renewable Energy (RE), their prospects, economics and technology. The Renewable Energy Information Network (REIN), being implemented under the Sustainable Rural Energy (SRE) project funded by UNDP and executed by Local Government Engineering Department (LGED), aims to remove the aforementioned barrier through an information platform with a comprehensive scope and long-term perspective.
REIN functions through it’s web-based interface with renewable energy related information tailored specifically to meet the needs of the general public, enthusiasts, energy planners, project developers, researchers, entrepreneurs, students and all other relevant organizations & institutions in developing renewable energy projects and promotion of renewable energy utilization in Bangladesh. It is expected that especially schools and universities can immensely benefit from the information services provided by REIN.
Renewable energy in Bangladesh
Renewable energy resources are highly site specific. For assessment of renewables, availability of micro-climatic data is essential. Some of the Institutes and Universities are looking into all possible renewable energy that could sustain the livelihood of people in this country.
Some examples of renewable energy that are abundant in Bangladesh are as follows:
- SOLAR ENERGY :
Bangladesh is situated between 20.30 – 26.38 degrees north latitude and 88.04 – 92.44 degrees east longitude which is an ideal location for solar energy utilization. There is bright prospect for applications of solar thermal and photovoltaic systems in the country.
- WIND ENERGY :
In Bangladesh, data from earlier measurements and analysis of upper air data by CWET India show that wind energy resource of Bangladesh is not good enough (>7 m/s) for grid connected wind parks [GEF 2001]. But, small wind turbines can be installed in the coastal regions of the country.
- SMALL HYDRO :
Bangladesh is a riverine country with three main rivers (1) Ganges (2) Brahmaputra and (3) Jamuna. Numerous rivers flow across the country which are mostly tributaries of these main rivers. This implies that there is a limited potential of small hydro power plants in the hilly regions and existing irrigational canal systems in the country.
- BIOMASSS :
Biomass in the most significant energy source in Bangladesh which accounts for 65% of the total final energy consumption in Bangladesh. The main sources of biomass fuels are – (a) Trees -woodfuels, twigs, leaves, plant residues (b) Agricultural Residues – paddy husk, bran, bagasse, jute stick etc. and (c) Livestock -animal dung. Waste-to-energy project should be given serious contemplation which will not only provide electricity, but also reduce the overwhelming waste disposal problems of metropolitan cities of the country.
- MARINE RENEWABLE ENERGY RESOURCES :
Bangladesh has got 710 km long coastal belt along the Bay of Bengal. Among the main marine energy resources, Tidal power can be harnessed in the near future if they become technically and commercially viable option.
- GEOTHERMAL :
Geothermal energy is the natural heat of the Earth. It is a renewable source of energy if the exploration process don’t hamper the ecosystem or emit greenhouse gases. There is a known hot salt water spring, known as Labanakhya, in Bangladesh at 5 kilometer to the north of Sitakunda (40 kilometer from Chittagong). Possibility of extracting energy from this site or any other unknown sites can be investigated by Satellite Remote Sensing or Physical Surveys.
These resources are the ones needed to be developed to improve further the lives of the Bangla people.
