Impacts of global warming and how green energy benefits the planet

The Green House Effect
In 1896, the Swedish scientist Svante Arrhenius came up with the theory that by releasing more CO2 emissions into the atmosphere, the planet’s average temperature would gradually rise through a term coined as the “greenhouse effect”. Originally seen as a being a positive effect of CO2 production, further research found that this rise in temperature could have catastrophic consequences for the environment, ecosystems and humanity. This concern resulted in an agreement being reached between multiple countries in which the represented states would decrease the CO2 emissions that they produced, and produce energy through ‘greener’ methods.
Air source heat pumps & wind turbines
Other green energy home products come in the forms of Air Source Heat Pumps and Wind Turbines. Wind turbines, more often than not, are used on an industrial scale, however, there have been a lot of recent developments in wind turbine technology meaning that there are now multiple ways to have a wind turbine installed in your home. Pole-mounted wind turbines are elevated from the ground, and when situated in a suitable position they can generate between 5 – 6 kW of energy. Another form of wind turbine is the building mounted turbine. These wind turbines can be erected on the top of your home. They are much smaller than the pole-mounted turbines, and as such can generate around 1-2 kW of energy. Both types of wind turbine can have a huge effect on decreasing the amount of carbon emissions that your home produces.
Reduction in carbon emission output
The development of low energy appliances also means a reduction in your carbon emission output. These appliances, such as LED light bulbs, require less electrical power to operate, resulting in less electricity being produced and consumed, less emissions, and less money spent on bills! These items also usually have a long life expectancy, meaning that they will not have to be repaired or replaced very often. Similarly, other appliances that use a couple of utilities – like a dishwasher requires electricity and water – focus on reducing the amount of both utilities. For example, washing machines are using less and less electricity and water, reducing both harmful emissions and bills!
Electric cars/CO2 emission free
It is not only your home that can be ‘made greener’, there are a variety of cars now available that are either partially or fully CO2 emission free. There are a few different types of fuel that can be used instead of petrol which give off no CO2 emissions. Electric cars are becoming more popular due to the ease in which they are recharged, and the mileage that they can get when they are fully charged. There are a number of charge points all over the UK where you can top up your vehicle, and more are created each year with the growing number of electrical cars on the road.
Another fuel type is hydrogen
More and more vehicles are being fit with hydrogen fuel cells as they high efficiency along with no CO2 emissions. These fuel cells work by combining hydrogen and oxygen together in order to create a chemical reaction to create water. This water then powers the engine by creating electricity through electrolytes. Because of this, the only by-product of the chemical reaction is water, no CO2 or other harmful chemicals are created. However, due to the lack of easily accessible hydrogen fuel, most of these vehicles use a hybrid fuel system where they are still able to run on petrol or diesel.
Every year new and improved ‘green energy’ products become available for use in home or at work, and, thanks to the research that has gone into these products, they are cheaper than ever to purchase, whilst at the same time helping to reduce your bills. Whilst all these are excellent reasons to look into making your home more green, perhaps the most important is to help to keep our planet safe for future generations.
