Thoughts on energy efficiency and sustainability

Image from TrustElement
It is quite evident that nations have not given much attention to the importance of energy conservation and efficiency from the past years. While world’s energy consumption has continued to increase over the years, the policies on energy efficiency and sustainability are often ineffectual and not properly implemented. And since energy is required for economic growth, it is just essential to have sustainable clean energy and improved energy efficiency.

Energy efficiency is defined by World Energy Council (WEC) as the overall changes due to reduction of energy usage for a given service or level of activity. But it does not necessarily mean that it is only because of technical changes, it can also be the result of a better organization and management or improved economic efficiency in the sector.

But how can we achieve improved energy efficiency?

By lowering or decreasing our energy consumption through effective energy policies and efficient technologies we can improve our energy efficiency. Since for every product/service produced there is an equivalent energy usage, the less energy consumed the higher the energy efficiency. Therefore, improved energy efficiency will result in improvement of production, total costs reduction and eventually—improvement of our economy.

On the other hand having improved energy efficiency is not enough for almost 7 billion people around the world. Energy problem couldn’t be resolve without both energy efficiency and sufficiency. Although it is possible for every nation to conserve energy, if the resources can’t support our present energy needs and of the future generation, then we can say sustainability is way too far achievable. As the term itself defines, sustainability is the ability to meet long term sustenance whether it is for individual needs or for a global scale. It is meeting the needs within the carrying capacity of supporting ecosystems without risking the ability of future generations to meet their own needs.

Importance of MRF – Material Recycling Facility

What is MRF? MRF or Material Recycling Facility also known as Material Recovery Facility integrates conveyors system which is used for material recovery or recycling. It has sorting machinery wherein it divides recyclables according to end marketable usage. Normally, there are two different types of MRF, the clean and dirty MRF’s. Significance of MRF As we know it, recycling is one method of conserving our natural environment. And MRF systems play an important role in doing the method of recycling in a large scale basis. As an essential component of innovative waste management system by means of recycling, MRF greatly helps in conserving the environment. It lessens the extraction of our natural resources thus creating a more sustainable way of manufacturing new products. Aside from that is decreases the amount of waste materials in our community thus prevents the spread of environmental contaminants that may also bring dangers in human health. MRF also offers high processin...

During typhoons, trees serve the environment as protection from flash floods. It helps preserve our soil and water by holding the soil in place to prevent soil erosion or landslides. Most of the products that are manufactured today are from the wonders of trees and shrubs.
