Green Living-Things to Consider

 

Are you really serious about Green Living and Going Green? Then, consider taking some big steps, what about changing a career and contributing to the development of the clean energy technologies? Clean energy  careers are hot, they are favorite choices of career for many students  who are attracted by many well-paid and in-demand jobs. Clean energy job would make you feel good and will benefit our mother-earth.

Going Green isn’t only about changing a lightbulb or buying expensive products. Going Green is a way of life, and has to do with our holistic approach to life. Our careful choices immediately have an impact on your health and, essentially, the health of our planet.

But don’t think that little things don’t matter! It just takes a bit of effort to go a long distance. Here you can find some tips to make your life a little greener. too.

What is Energy and Forms of Energy

Energy, in all its forms, belongs to the most fundamental elements in our universe.

We are using energy to live or to do work, our cities are lighted by energy, our vehicles are powered by energy, as are trains, planes, boats, and rockets. We use energy to warm our homes, to cook our food, to play our music, or to watch television. Energy is needed to power a tractor on a farm or to allow machines in a factory run.

Nonrenewable Sources of Energy – What are they?

Nonrenewable sources of energy are the ones that have a pre-existing finite amount of ‘fuel’, and by “fuel” is meant any kind of substance that is storing energy. Natural gas, gasoline, uranium, kerosene, and firewood, all these substances are ‘fuel’ examples. And of these ‘fuels’, firewood is the only renewable is this listing. Here are the most common nonrenewable fuels:

Fossil Fuels: Oil, Coal, and Natural Gas – These fossil are what is left over from animals and plants that were living several millions of years before us. This is why they are called ‘fossil’.  All these fuels are ‘carbon-based’ meaning they are consisting mainly of elements that contain carbon and hydrogen coming from these ancient animals and plants’ bodies. Oil is a fossil fuel in liquid form (where each molecule contains several carbon atoms), natural gas is fossil fuel in gaseous form (where each small molecule contains just 1 or 2 carbon atoms), and coal is fossil fuel in solid form (each molecule contains many carbon atoms).

Why Renewable Energy Is Not Popular

What obstacles keep us from switching to renewable energy?

Stranded Cost: Across the US, we already have been paying some one trillion dollars for the infrastructure for fossil fuels. There are people who say that, if we were to switch entirely to renewable fuels, this huge investment could be ‘stranded’, unless we would find ways to include it. This is why there is opposition against switching to renewable fuels as this would create a huge economic disincentive. There are others who argue that abandoning this existing infrastructure gradually would be a lot cheaper than giving it up immediately. 

What is Solar Power?

How much of our energy is coming from the Sun

In Direct sunlight, the sun is providing around 90 watts per square inch at the surface of the Earth, or 1000 watts per square meter. The intensity that this refers to is what energy scientists call 1 sun, and is .  sufficient to power ten 100-watt light bulbs, or fifty 20-watt fluorescent light bulbs. As opposed to what is sometimes claimed by solar energy opponents is solar power not at all weak or diffuse. The amount of sunlight that falls on even a tiny portion of a home’s roof is in general actually already enough to take care of all the home’s energy needs. Or said in another way, if we would cover not even 1 percent of all U.S. land area with solar power panels, we could be providing all of our current energy needs.

Ocean Energy

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.

PowerBuoy

The PowerBuoy is the wave energy device designed by Ocean Power Technologies (OPT). There are two larger scale PowerBuoys currently in development. They are known as the PB40ES and the PB150. The PB40ES is a 40kW utility scale device that is capable of generating a sustained maximum output of 40kW.  The PB150 is the company’s first utility scale PowerBuoy with a 150kW rating. It is being made in Scotland and will be tested at the European Marine Energy Centre, Orkney. The size of the PB150 is 115ft tall by 46ft beam.

How It Works

The PowerBuoy works as the rising and falling of the waves causes it to move up and down. The resultant stroking action is converted by a power take-off to drive an electrical generator. The power that is generated is transmitted ashore via an underwater cable. The PowerBuoys generate power when the wave height is between 1.5 and 7 metres and sensors will detect waves that are too large and will shut the system down automatically.
