What is renewable energy?

Renewable energy is an infinite energy source.  Essentially, power can be produced over and over and never runs out, and is usually harnessed from the many forces of nature.

Below are eight types of renewable energy sources available, as well as a brief explanation of how they generate power.

Wind

Wind turbines turn kinetic energy from the wind into an electric current.

Solar

This is where sunlight is captured through solar panels and converted into electricity.

Tidal

The movement of tides generate turbines which in turn generates energy. This is probably one of the most reliable renewable energy sources compared to wind and solar.

Wave

Wave energy captures the force of wind generated by waves.

Hydrological/hydroelectric

This is energy harnessed from the movement of water in rivers, lakes and Dams.

Geothermal

This uses the natural heat of the earth in volcanic regions.  Water is pumped underground which is then converted into steam.

Biomass

This is organic material which can be burned and used as energy. Examples of this include rapeseed which is converted into oil, then after treatment can be used as fuel in diesel engines.  This energy type is sustainable if crops are replanted.   

Wood

Trees are cultivated and chopped down and burned to generate heat and light.  This is deemed as renewable if trees are replaced, although this energy source is not very environmentally friendly as burning of wood emits Co2 which contributes towards global warming, unless trees are replanted to absorb the harmful gases emitted.

How can I make a difference?

With the rise of fuel and utility costs and the threat of global warming evermore in the spotlight, renewable energy is fast becoming the cheaper and cleaner alternative to traditional fossil fuel sources such as oil and gas. 

If you are considering renewable energy in order to reduce your heating bills and to decrease your carbonfootprint, there are many options available for homes and businesses, including:-

Biomass boilers – These use wood as a fuel source.  As long as the wood is from a sustainable source, these are very environmentally friendly as newly replanted trees absorb carbon dioxide which is released from burning wood.  The government set up a scheme called ‘Renewable Heat Incentive’ which pays for every kWh of heat produced by a biomass boiler.

Air source heat pumps – These absorb heat from the outside air which can then be used to heat water and radiators.  These devices can extract heat from the air, even if the temperature is as low as -15c!

  

Solar Panels - So far, 450,000households in the UK have solar panels installed, making it one of the most popular choices for renewable energy.  Solar panels capture the suns energy which is then converted to electricity.  Since solar power is a green energy, it doesn’t release any harmful toxins into the atmosphere and is very reliable, providing you have a south facing roof on your home in order to capture the maximum amount of light.

Solar thermal heating systems - Unlike solar panels which capture the light, solar thermal heating systems uses the heat from the sun to heat water in domestic and commercial premises.  The performance of these devices depends on climate, so if there is a cold weather, the extraction of heat from the sun may be impeded.

These are just some of the ways that householders and business owners can help the environment and save money, however simple changes such as watching your energy consumption and being mindful about the products that you buy, will mean you are making a difference for your finances and the planet.

Dubai Is Going Green

Dubai is one of the emirates in the UAE. For someone who has not been in this place, the common picture they will imagine is a city in the middle of the desert. It is actually that - a city in the middle of the desert but a green city.

The streets of Dubai are lined up beautiful small bushes and flowering plants while major thoroughfares are teeming with palm and date trees. The roundabouts are adorned with green plants and major bridges and overhead passes have small pockets of well-tended landscaped gardens. All these plants are watered round-the-clock and are installed with timers to allow sprinkles to work on cue and water to pass on resistoflex teflon hose.

Cosmopolitan Dubai has also placed across the city various recycling receptacles which are visible to everyone so proper disposal of recyclable items is encouraged. A lot of malls also have big bins for electronic devices and batteries for proper disposal.

Companies have followed suit by putting their own distinguished bins all over their offices. Our company supports the government's drive to keep Dubai green. Each station in our office has cardboard boxes used for paper disposal and it is collected regularly by a uniformed personnel who takes them to the recycling plant.

Kids in school are being educated on the benefits of recycling, reusing and reducing wastage. Activities such as beach cleaning is a regular event in schools and other companies during the colder months to help clean the environment and promote a greener lifestyle.

I believe Dubai will achieve the green drive as long as the people are educated about the importance of going green.

Go-Green Shopping

When visiting other countries, try your very best to check out the local markets, small stores and the off-the-beaten-path stores and see their produce, goods and handicrafts as well rather than going to the city malls and department stores. By going to these local markets, you are helping to support the local business.

Baby Goes Organic

In this age of global industrialization, a lot of companies and people are opting to go green to help our ailing Mother Earth recover. I have gone where others fear to tread and that is by going green! I am a happy "green person" and I try my level best to suit my activities and uses of products (and even services) which will aid in promoting environmental awareness.

I have cut back on my travels this year to minimize our families carbon footprints. We have switched to green lights and jute bags. I now put my sandwiches on glass containers so it can be washed again and again.

Even some of my families clothing have undergone revamp. I started purchasing clothes which are made of organic materials. We all know that organic materials are almost free of chemical abuse. Next to follow my lead will be my relatives and their kids and my friends as well.

I found this site which caters to Organic Baby Clothes. Their sense of style and whimsical designs are my kind of stuff. I browsed their products and found many Cloth Diapers and Baby Onesies. You can choose from various cute designs and even put text as you wish on the clothes you want. Since most of my friends live in the US and Canada, I think the long sleeves onesies will be the best bet as a gift.
