Energy Utilization - Science topic

Energy Utilization and Automation " > Utilizatopn versus Automation -scope not cleare

Renewable energy is, without a doubt, one of the main energy sources used by many countries for electricity generation and the cleanest type of energy source available in the world. However, and despite practical and convincing technologies on renewable energy available for its use for elctricity generation, the process to switch from the use of non-renewable energy sources to the use of renewable energy sources has been quite slow and uncertain especially in the developing nations. Some of the main barriers to be faced in this process are, according to Dorcas Kariuki, the following:

· over-reliance on fossil fuels (coal),

· political and regulatory barriers,

· technical barriers,

· market-related barriers,

· social-cultural barriers,

· financial and economic barriers,

· geographical and ecological barriers.

Dear respected Cristian Acevedo,

Mechanical engineering is helpful in the area of material selection in development of the various parts of renewable energy equipment and machine.

Best regards.

Look at this doc it may be helpful for your topic. Good luck.

Dear Karima,

After setting the initial energy of your nodes, you need to update it according to an energy model such as the first order radio model or the discrete radio model. You need to select the energy model most appropriate to your nodes and application at hand.

Are you referring to the Paris agreement that was recently signed? 

If I recall correctly, no carbon tax, nor cap-and-trade schemes were part of the agreement. It only states that nations commit to reducing GHG emissions. Each country will have to submit a plan that outlines how they intend to do so. 

In any case, most of the carbon emission growth comes from large developing countries such as India and China. If substantial reductions in GHG emissions are to be achieved,  it is essential for these important countries to be proactive. 

To what type of energy do you refer?

Electromagnetic energy? thermal energy? chemical bonds? kinetic energy?

Or do you mean psychological "energy" / resilience / self efficacy?

Or yin and yang, or Chakra alignment??

I'm sorry but until terms are defined I honestly find it difficult to understand what your question means.

 Thank you so much for your contributions. Actually, I am working in an energy balance of this industry, but it is mainly theoretical, so I wanted to have some values for comparison because I am using some assumptions that might be a bit unreal. I will have a look to this material

Drea Krishnan,

The attached paper is very interesting and could be helpful!!

The gap is generally defined as the difference between the measured and the theoretical energy performance. To get this figure, it should be ensured that both measured and calculated performances  have the same boundary for the energy balance and are determined in the same way. The standard EN ISO 15603 proposes measurement and calculation methods that should provide the same result if the simulated inhabitant behaviour is the same as the actual one.

Some building energy authorities (e.g. the Swiss ones) consider that the gap results from inhabitants behaviour only. Amazingly, they implicitely admit that the true energy perfromance is the theoretical one! Indeed, the gap may also result form modelling or calculation errors, or from  differences between the modelled building (based on the design) and the one actually built.

The truth is there is no straight forward answer to your question.  deployment strategy depends on several factors of which application area, sensing area and node density are the major factors. Is it a multi-hop ad-hoc network ,which is the most common form of WSN. Will they be static or dynamic or self-configured network?

If grid is efficient in one application, star topology with clustering may be efficient in another. To find an optimum solution, (not depending on the obvious) one may need to test uniform or grid based and random distribution patterns and see which is more energy efficient.

If speaking about energy consumption in cold climate for space heating:

Despite the indor and outdoor climate conditions, most influencing factor is ocupant behavior. Building ocupants can adjust indoor temperature, air change rates and internal gains.

More efficient building comes - higher influence ocupant behavior impact gets.

Level of influence could be easily assesed by heat balance equation. When envelope transmision losses decreases and building thermal constant rises - weight of balance members influenced by human behavior starts to grow. (Heat balance equation presented in European standard EN 13790)

Weight of influencing factors must vary and depend on outdoor climate conditions
