#Lessons From ESOS Energy Legislation In The UK The U k. recently announced compliance guidelines for the government new Energy savings Opportunity Scheme (ESOS), a mandatory energy assessment and energy saving identification
The objective of ESOS is to reduce energy consumption, help address climate change, increase energy security and improve the competitiveness of U k. businesses.
and administered by the Environment Agency intended to trim excessive energy use as a means to cut carbon
while mitigating organizational energy waste. In short but not-so-simple terms, qualifying businesses are required to a) measure total energy consumption, accounting for 90 percent of usage across all buildings, transport and industrial activities;
b) conduct energy audits to identify cost-effective, energy-efficient recommendations; c) ensure that the ESOS assessment has been conducted
or reviewed by a board-level director and approved by a lead assessor; and d) report compliance to the Environment Agency by December 5, 2015.
certain caveats exists there is no obligation to implement these energy saving measures internally identified in the audit,
Though the legislation notable feature appears spineless by failing to require businesses make any of these recommended changes to save energy,
participants must demonstrate an authentic and rigorous attempt to examine opportunities for reducing energy use and have reviewed these findings at the board level.
The Challenge to Measure and the Burden of proof While companies may find motivation for implementing the recommended energy saving measures of the audit solely for financial benefit,
the ESOS directive is as much about enforcement as it is about the need for companies to understand power consumption.
Uncovering pockets of energy waste requires appointing personnel familiar with the scheme; the only other option is to outsource,
the vast majority of businesses lack the technology to accurately track such energy consumption. Measuring the energy consumption of a Macbook Air compared to that of a Dell Desktop PC,
for example, will prove to be difficult. While some organizations already have the Microsoft System Center Configuration Manager (SCCM) in place
allows companies to reference the power consumption of each device, along with the actual power usage when on and off.
taking into consideration that the U s. wastes an approximate $2. 8 billion in PC energy every year, the U k. may need to take a more effective approach to energy security.
Recognizing the additional administrative pressure placed on energy managers with ESOS which will have many similarities to existing U k. policies the government is proposing that enterprises be allowed to utilize data from other schemes,
According to the American Council for an Energy-efficient Economy, even China and India have fared better on the list than the U s as American energy regulations for power conservation have been particularly scarce in recent years.
Ideally, a partnership between U s. government and industry is essential for an energy policy to have a significant impact on the future of businesses and the environment.
As the U s. continues to rank among the top three energy consumers in the world,

#Blame the Weather for Last Year s Rise in U s. Carbon dioxide emissions A colder winter was one of the main reasons carbon dioxide emissions from energy use rose in the United states by 2. 5 percent in 2013
, according to new data from the Energy Information Agency. Besides a small rise in the price of natural gas and slightly cheaper coal, the weather played the biggest role in in pushing up emissions,
there were 18 percent more days in 2013 cold enough to cause a spike in demand for energy for heating,
This contributed to an 0. 5 percent increase in the amount of energy used per dollar of GDP,
More coal and less gas meant a much smaller drop in the U s. energy system arbon intensity?

and the hydrogen can be used to replace fossil fuels not only in electricity production but also in industry and transportation
Even so it has long been considered a relatively lousy way to store energy because of its low efficiency about 65 percent of the energy in the original electricity is lost.

#Sharp Demonstrates Ultra-Efficient Solar cells The best solar cells convert less than one-third of the energy in sunlight into electricity
when sunlight strikes a solar cell it produces some very high-energy electrons but within a few trillionths of a second those electrons shed most of their energy as waste heat.
