There is no dearth of job opportunities in the renewable energy sector. There is also great variety when it comes to renewable energy careers. This may often make it difficult for prospective employees to choose their professional niche. This also makes it possible for people from various backgrounds to make their foray into the field. Interested candidates may even undergo professional training to become a part of the industry.
Like any other sector, renewable energy recruitment also has much room for people from diverse backgrounds. These include marketing, communications and other fields of business support. There are diverse aspects of business and various other tasks associated with it. These include accounting, corporate planning, information technology, business law, finance and human resources.
Apart from these, career opportunities abound in diverse fields of renewable technology sector. Opportunities in the sector are available in the fields of wind power, photovoltaics, solar power, hydropower, geothermal energy and bio-energy.
We all are concerned about climate change and the effects we already experience. But what if Global Warming is a natural phenomenon? Many people claim that on our planet, warmer and cooler periods have occurred for as far back as we are able to determine.
Periods of Global Warming have occurred some 100,000, 200,000 and 300,000 years ago, and scientific data has been obtained from proxy sources including sediment layers and rocks, ice cores, tree rings, and coral reefs. Compiling all these data allows us to determine temperatures millions of years ago.
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.
Upfront Cost: There are renewable sources (wind power, hydropower, and geothermal power) that are currently (practically) competitive with fossil fuels, but solar energy continues to be pretty much more costly than coal-based electricity. The budgetary mechanisms to that allow renewable fuel systems to be paying for themselves in a natural way simply do not exist yet.
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.
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 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).
