Advantages of Renewable Energy at Macro and Micro Level

Posted in Energy Economy | Energy Industry | Future Technology

Renewable Energy It is now certain that the current energy systems and technological advancements available in the world are not sufficient to make the planet free from the carbon dioxide that is emitted from those resources. To solve this problem, there is a scope to build new technologies and to bring the existing technologies together to get maximum benefit from the entire energy system including energy production, transformation, to energy transportation and distribution. Work in this direction will have to be taken at both macro and micro level.

Need for renewable energy resources

The world will have to switch to renewable energy resources very fast, because despite the availability of renewable energy resources, a large part of the world is still dependent on traditional energy sources such as coal and gas. This over-dependence of these traditional resources will lead to a situation where by the end of 21st century, resources like coal and gas will become extinct from the world. Thus, continuous efforts need to be made to switch over to renewable energy resources. This switch can help many countries make a successful environment policy and reduce the consumption of imported oil and gas.

Use of energy resources with low carbon at macro level

If Risø National Laboratory for Sustainable Energy is to be believed, by the year 2050, the world will be in a position to use sources of energy with very low or no carbon emissions. The global energy system with low emissions will now have to use this new energy system in such a way that the cost of using these resources is also reduced.

The Risø energy report 9 gives a list of a number of energy technologies that will be commercially available for use in times to come. These technologies with no emission of greenhouse gases will help in reducing pollution.

The Risø energy reports, which have been prepared by the joint efforts of Danish and international experts look at energy issues of today and tomorrow from the perspective of the needs of Danish people, the region and the world. These reports are monitored by an independent panel of international experts and are based on scientific material that is internationally recognized.

Use of energy resources with low carbon at micro level

The new technologies in energy sources have to reach the end user. The producer should keep in mind what the users want at the local level and make technological advancements in the goods being used by the common person on a more regular basis. New technologies are being used in items like electronic equipment, heat pumps, local energy supplies such as solar cells and energy storage that people use on a daily basis.

Use of renewable energy resources in Denmark

In countries like Denmark, there is a strong need to start encouraging renewable energy systems right away. This will have several advantages like,

  • It will help to eliminate traditional fuel like gas and oil at a very fast pace
  • It will reduce the emission of greenhouse gases
  • It will help to stop the use of traditional fuel in generating power and heat production by the year 2040.
  • It will help to eliminate the use of gas and oil in the transport sector in Denmark by 2050.

There is a need to invest and take maximum advantage of the developments taking place in renewable energy sector. If we do not invest in this sector and make use of the opportunities given to us, it is likely that the scarcity of traditional resources will put so much pressure on the generations to come that they will never be able to bear.

    Obvious, and inevitable if, say, a hundred year+ timespan is considered. But time is running out since a start, beginning ‘yesterday’, is needed to meet world needs. A forthcoming article in altenergymag.com aims to explain further. Solar greetings, Mike

    Wind and Solar schemes are still very expensive supplements and NOT alternatives. We need a breakthrough.

    In order to find a breakthrough we need DOE to offer a $1 billion PRIZE for “clean, affordable electricity.” Call an Energy Summit and review technologies – if one fits award the prize and share the IP.

    Not a bad article, although I can do without the “Save the Children!” posturing at the end.
    I do have exception with one part of the article. Where you state, “…by the end of 21st century, resources like coal and gas will become extinct from the world.”
    I do not believe so. I believe those resources will still exist, however, they will become so monumentally expensive to extract, no one will be able to afford them.
    Supply and Demand – as the supply dwindles, prices drive up to control the demand. The overwhelming majority of people on the planet will simply not be able to afford oil or coal as energy options.

    I’d like to reply to AndrewW: Just not true. There is enough evidence existing on the ground since years. Just an inkling of what’s what is on my blogsite.

    The world today has an even greater increase in its demand for energy. This is due mainly to the rapid growth of population, which has more than doubled in the last 50 years. This has caused a strain on our energy supply, which has led to an increase in energy costs as well as shortages in many parts of the globe. Conventional energy sources such as petroleum and gas are said to have been dwindling significantly and has the possibility of running out completely in the future. This has encouraged many people to look for alternative energy sources one of which is renewable energy.

  • AndrewW

    Well, Michael I appreciate your website but DOE says wind and solar generated electricity are $.18-$.39 per kWh. That’s not affordable, it is an expensive, highly subsidized supplement.

    We need a breakthrough instead of wasting billions on overpriced and underperforming wind and solar schemes.

  • http://cleanenergypundit.blogspot.com L Michael Hohmann

    Reply to AndrewW: perhaps your DOE means what it says, but have you looked at the examples I show towards the and at
    http://www.lmhdesign.co.uk/sustainability.php ?

    In Germany the hidden subsidy for nuclear power is about $3.40 per kWh and utility companies are quoted as making a profit of $2million from selling electricity from a single nuclear power station — per DAY.

    Compared to that, a local authority (Planegg — just one of many) in Germany is generating its own power costing less than grid electricity.

    “In Germany the hidden subsidy for nuclear power is about $3.40 per kWh and utility companies are quoted as making a profit of $2million from selling electricity from a single nuclear power station — per DAY.”

    Gosh!! – You’d think they’d be scrambling to build more with a subsidy like that. I wonder what the source of this number is. I pay about $.12 / kWH here in the US.

    A profit of $2 million per day is not unheard of when you consider the enormous amounts of power generated by a nuclear power plant. Lets say the plant is rated at a gigawatt. This is equivalent to maybe a thousand wind turbines and the plant will generate continuously at that rate unlike the wind plants. In addition since the plants are old, the capital cost will have been paid off. (The plants are paid off.) The plants are able to make a great deal of greenhouse gas free energy and make money at the same time.

    “The world will have to switch to renewable energy resources very fast, because despite the availability of renewable energy resources, a large part of the world is still dependent on traditional energy sources such as coal and gas.”

    In addition to renewable power, I predict that nuclear power will be one of the choices applied by future generations once the public overcomes its fear.

    It is agreeable that people should switch to using renewable energy systems. This will have a big impact to the environment as to reduce the emission of greenhouse gases and eliminate the use of traditional power and heat production.

    I guess I have a hard time believing that the shortest path is at the utility level. I recently interviewed an engineer who placed commercial solar on his roof and tightened up his envelope. His ROI is 10 years. (with the TVA green energy buy back) It appears simple to me that if we all build our own rooftop plants and invest in our own houses, the selfish thing to do becomes the selfless thing to do.

    There is no need to wait for new technology.

    What would happen to our carbon footprint if all residential electricity was generated at home? What would happen to the economy if everybody got busy today? What would happen to the cost of heating oil if we stopped using it for residential consumption? If we instituted a low cost loan program so that everyone could shift the cost of electricity to debt service, anybody could afford it. Power plants would only have to supply electricity at night and on cloudy days. We would come home every night and plug our electric cars into the grid using energy we produced earlier in the day. Before long, our cost of fueling our cars and our homes would be close to zero. What would that do to the grid? Wouldn’t that solve all the problems short term while utilities raced to reduce the cost of renewables?

    I disagree with Andrew, there are countless solar and wind energy systems that have been installed and are integrated to output performance.

    On the East Coast, to take New Jersey, New York, and Pennsylvania for example, residential customers have a payback period of 4 years. With a total cost of 0.05 cents per kwh over the total life of the system (25 yrs)…

    Its not rocket science…Its fact. I agree that solar and wind energy systems are supplemental,and a breakthrough needs to occur in emerging technologies that would still seek to harness what is available “naturally.” Does anyone have a flux capacitor? 😛
