The best and worst countries in the world when it comes to air pollution and electricity use

China steals an unsavory global spotlight for the thick, noxious smog that often chokes its mega-cities.

Air pollution has become so bad in Beijing, for example, that Chinese officials aim to slash its local coal consumption by 30% in 2017.

original-2 original-3 original-4 original-5 original-6 original-7 original-8 original-9 original-10 original

Meanwhile, the US — which currently ranks eighth on the list of countries with the lowest air pollution — could be headed in the opposite direction.

President Donald Trump has said that he intends to fulfill his campaign promise of revitalizing the American coal industry, despite the criticism of fossil fuel industry analysts and the rise of affordable sources of renewable energy. Congress is also working to repeal environmental regulations.

With these and other changes afoot, it’s worth taking a look at current global rankings to see how China, the US, and other countries stack up when it comes to air quality, total energy use, and renewable contributions to power production.

Here the best and worst of 135 countries according to World Health Organization (WHO) and International Energy Agency data, which was shared with Business Insider by The Eco Experts, a UK-based solar energy comparison site.

There are many ways to measure air pollution, but a key indicator is called “PM 2.5” — one of the most harmful classes of airborne pollutants. The “PM” stands for “particulate matter,” and the “2.5” stands for 2.5 microns in diameter or smaller — roughly the size of a single bacterium. Such pollution, as Business Insider’s Lydia Ramsey explained in 2016 , “is especially dangerous because it can get lodged in the lungs and cause long-term health problems like asthma and chronic lung disease.” When PM 2.5 levels go above roughly 35 micrograms per cubic meter of air, it can become a major health problem. The WHO recommends keeping PM 2.5 levels to about 10 micrograms per cubic meter.

Air pollution levels are one thing, but deaths attributed to them are another. Take China, for instance. The country isn’t in the top 10 for highest average levels of air pollution, in terms of PM 2.5 (Saudi Arabia wins that contest, thanks in part to its oil industry ). However, it ranks fifth for having the most deaths per capita due to air pollution, in part because if its high population density. The US currently has one of the lowest death rates attributed to air pollution.

Decades of scientific work across multiple lines of evidence corroborate a powerful yet inconvenient truth: Human-caused global warming and climate change is real , and it’s briskly accelerating as we dump more carbon emissions into the atmosphere. Looking at per-person average emissions of carbon dioxide, a persistent greenhouse gas emitted by burning fossil fuels, the US ranks as the eighth-highest contributor in the world. Less developed nations, which lack robust and power-hungry infrastructure, rank among the lowest contributors to carbon dioxide emissions.

The main reason the US ranks so poorly on carbon dioxide emissions is because its per-person consumption rate of electricity is so high; all of that energy comes primarily from fossil fuels. As with carbon dioxide emission rankings, less developed nations tend to score better on electricity consumption because access to electrical power is not as widely available.

Despite their poor rankings in air pollution and electricity consumption categories, China, India, and the US are the top-three contributors to renewable energy. The ranking here is in “tonnes of oil equivalent” or TOE — meaning renewable energy sources generated (and presumably replaced) the energy created by burning that many metric tons of oil in a year. Four Middle Eastern nations — Qatar, Kuwait, Bahrain, and Oman — are tied for “worst” in this category, since each had a “0” in TOE contributed by renewables. However, they are not shown in our graphics because this may be due to a lack of available data (all four nations are actively pushing growth in renewable energy sources ).

Exemption of Electricity Duty to Open Access consumers who are exempted to pay Electricity Duty. MSEDCL


Maharashtra State Electricity Distribution Co. Ltd.

Maharashtra State Electricity Distribution Co. Ltd.

Prakashgad, Plot No.G-9, Sandra (East), Mumbai – 400 051



P-Com/Accts/EDI                                                            DEC 2016]

All superintending Engineers                                                                                                        ‘

O&M Circle MSEDCL.

Sub :- Exemption of Electricity Duty to Open Access consumers who are exempted to pay Electricity Duty.

Ref :- 1) Maharashtra Electricity Duty Act. 2016 amended vide GoM Resolution dt. 08.08.16

  • GOM Notification 31.08.2016.
  • Office Note P-Com/Accts/ED 1341 dt. 02.11.2016

In connection with above that as per GoM resolution dt. 08.08.16 the electricity duty has been charged on the consumption wef Sept.2016 onwards to all open access consumers as above except consumers of Vidahabha & Marathwada region.

Thereafter, MSEDCL received several representations from OA consumers and RE generators who are already exempted for payment of Electricity Duty as per the eligibility certificate granted by GoM.

As such, it has been decided that, the MSEDCL will stop levying the electricity duty to such OA consumers and RE generators who are exempted from making payment of Electricity Duty in bills issued and being issued from December 2016 onwards, till further instructions from GoM/Hon’ble High Court Mumbai in this matter

Accordingly, the instructions has been issued to IT for not levying the duty to exempted consumers with instructions to credit amount of Electricity Duty recovered from such consumers from the month of Sept. 2016 to NoV.2016 & Dec.16 in Jan.2016 bill. Now some of the bills are already issued and they have already made the payment of their bills. However, if any consumer willing to pay the bill excluding the amount of electricity duty then such payment may be accepted as per revised bill from IT for the month of Dec.16. It is directed to not to take any corrosive action on such OA consumers who have not paid Electricity duty amount on OA quantum.

If any of such consumer who has made payment of bills excluding Electricity Duty of OA quantum and is eligible prompt payment discount & related load factor incentive will get his anticipated benefit and detail instructions are already given to IT in this regard. It will be applicable to only Electricity Duty exempted consumers.

Further, as per the RE Policy of the Government of Maharashtra RE generators are under exemption to pay the electricity duty for the period of 10 years as per GoM notification. As such the details of such RE generators are required to update in the system for extending them the benefit of GoM’s policy.

You are therefore requested to take note of above and inform the details of date of commissioning of RE generators of all open access consumer under your circle so that their exemption period can be fed to system and RE generators already completed 10 years can be identified for charging the electricity duty.

Power loss due to soiling on solar panel: A review

The power output delivered from a photovoltaic module highly depends on the amount of irradiance, which reaches the solar cells.

Many factors determine the ideal output or optimum yield in a photovoltaic module.

However, the environment is one of the contributing parameters which directly affect the photovoltaic performance. The authors review and evaluate key contributions to the understanding, performance effects, and mitigation of power loss due to soiling on a solar panel. Electrical characteristics of PV (Voltage and current) are discussed with respect to shading due to soiling. Shading due to soiling is divided in two categories, namely, soft shading such as air pollution, and hard shading which occurs when a solid such as accumulated dust blocks the sunlight.

The result shows that soft shading affects the current provided by the PV module, but the voltage remains the same. In hard shading, the performance of the PV module depends on whether some cells are shaded or all cells of the PV module are shaded. If some cells are shaded, then as long as the unshaded cells receive solar irradiance, there will be some output although there will be a decrease in the voltage output of the PV module. This study also present a few cleaning method to prevent from dust accumulation on the surface of solar arrays.
