“Water, water everywhere, and not a drop to drink!” When a fact, that 70 percent of earth’s surface is composed of water, is well-established, then it seems hard to reason the global cry to conserve water. However, interestingly there are regions in the world where this apparently bounteous resource is just not available enough. Well, this is because another hitting reality is that 97.5% of all the water available on earth is simply not fit for human consumption. Only a meagre 2.5% of earth’s entire water is consumable, with one third trapped in the form of glaciers and polar ice. Thus, water left for human use is hardly 1% of the total water available.
With such a small portion of existing water being fit for consumption, there is no need to further justify the arising need for water conservation and purification. With the world population growing at an uncontrolled rate,
In January 2013, the UK government launched an innovative and promising financing mechanism, the Green Deal, heralding an energy efficiency revolution in the UK. The Green Deal is an interesting model that reduces the burden of upfront costs for energy efficiency improvements in households by offering loans that can be paid back through cost savings achieved on energy bills. The scheme is valid for both domestic and non-domestic sectors, and is expected to replace existing policies like the Carbon Emissions Reduction Target (CERT) and the Community Energy Saving Programme (CESP).1
The Green Deal also has an underlying caveat, ‘The Green Deal’s Golden Rule’, which is considered the backbone of the scheme. The rule clearly demands that the energy savings a property makes in the 25 year period after the adoption of energy efficiency measures must equal or exceed the entire initial cost of installing the improvements. Furthermore, the rule dictates
In the wake of the recent growth of nanotechnology manufacturing, along with extensive research and development being conducted in a rising number of laboratories across the globe, the public and private sectors are becoming increasingly attentive to the majorly untapped potential of nanotechnology application across a myriad of sectors.
Nanotechnology comes with a promise to develop innovative products and improve the performance of existing ones across sectors. The technology offers interventions in a variety of domains like water, energy, health, agriculture and environment.1
Green nanotechnology is all about developing products and associated processes that are good for the environment. The green products of nanotechnology have either direct or indirect environmental applications. Direct environmental applications include monitoring using nano-enabled sensors, remediation of hazardous waste sites with nanomaterials, or treatment of wastewater and drinking water with nanomaterials, among others. On the other hand, indirect environmental applications result in energy savings linked with either
