Much of the the technology and ingenuity required to seriously reduce the threat of global warming already exists, and this includes solutions that are going to stimulate the American economy because they will be creating jobs, saving consumers and government money, and will be helpful to protect our national security. The key is sustainable or renewable energy.
By committing to and investing in renewable energy and, just as important, energy efficiency of appliances we use and the cars we drive, we can take significant steps towards minimizing our dependency on fossil fuels. We know that our consumption of oil is contributing to the threat of global warming. We should, and are capable to, use energy much more efficiently and benefit from much more renewable energy sources, including wind, solar, geothermal, and bio-energy. We must rapidly work towards a significant reduction of emissions of heat-trapping gasses, like carbon dioxide (CO2) methane, and nitrate oxide. We need well-educated executive managers who are ready to go all the way.
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 bioenergy.
There is also a lack of skilled workers in the renewable energy sector. People from diverse backgrounds can become a part of the sector at any point of time. But if you begin your career in the field, then you can learn the ropes of the trade after doing the groundwork well.
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.
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 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.
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.
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.
