The UK is embracing the digital revolution like never before but could this jeopardise efforts to keep carbon emissions in check, writes Guy Petheram.
In last week’s budget, George Osborne announced funding for the technology industry, and in particular digital research. This follows the announcement last month by the 5G Research Centre at Surrey University that they had managed to achieve a mobile internet speed of 1-terabit. The number is many thousand times faster than the current average 4G speed in the UK of 15-megabit.
There’s a long way to go before these mobile speeds become an everyday reality but the research is moving fast. Samsung announced only in October 2014 that they had clocked, what now appears a somewhat paltry, 7.5-gigabit.
For the government and investors that stumped up the £40 million to set up the 5G Research Centre in 2012, the direction of travel is clear. Wireless communication is a big part of the economic future, and smart cities and the internet of things are on the threshold of reality.
The demand for mobile devices such as smartphones and tablets shows no sign of abating. In 2013 their number exceeded the population of the planet for the first time, at around 7 billion. It is estimated that by 2020 there will be between 50 and 100 billion mobile devices.
Even without 5G, global mobile data (3G and 4G) grew by 69% in 2014 and is predicted to grow 10-fold by 2019. With 5G potentially becoming available by 2025, the exponential growth of mobile data will continue.
What does this mean for the energy consumption and the carbon emissions of an industry already under pressure to clean up its act?
To date environmental focus has been on the huge data centres that house the growing number of internet servers. A New York Times report in 2012 exposed the dirty secret of what is usually perceived to be a clean digital industry. They estimated that data centres consume the electricity equivalent to the output of 30 nuclear power stations.
However, it is estimated that the digital economy uses around 10% of the world’s electricity, with data centres responsible for only around one tenth of that. The rest is accounted for by the end user devices and the networks that link them back to the data centres.
An analysis by the Centre for Energy Efficient Telecommunications (CEET) in 2013 forecast that between 2012 and 2015 energy consumption of the wireless cloud would rise by 400%. That would represent an increase in carbon footprint from 6 million tonnes to 30 million tonnes.
Those figures also showed mobile internet data was the single biggest contributor. This may have something to do with the fact that compared to other forms of wireless communication, such as public or private WiFi, the mobile internet is power hungry. According to one recent analysis, it uses as much as 10 times more energy to download the same amount of data.
The potential for 5G technology to add significantly to global energy consumption, and therefore CO2 emissions, seems clear. The increasing speed of 4G technology is already predicted to lead to a huge increase in mobile video thereby massively increasingly the amount of mobile data traffic.
There are considerable efforts underway to improve efficiency in the digital industry. Companies such a Facebook and Google are increasingly turning to renewable energy to power their data centres and technological advances will undoubtedly mean more low energy devices in the future. Smartphones, for instance, currently waste up to 70% of energy consumed as heat.
The internet of things, in part enabled by faster mobile internet, is already making savings for businesses by making their energy use more efficient. Ultimately this hyper connected world could improve efficiency in a huge number of ways, from controlling our thermostats to reducing the time, and therefore petrol, it takes a driver to find a parking space.
However, in a statement about the potential benefit of the internet of things the International Energy Agency said, “Alongside all the benefits there is also potentially a very steep energy cost to pay. To ensure that the step forward does not equate to the need to install a lot of new electricity generation plants, it is not enough to reduce the devices’ power demand. Instead, new ways of powering these devices and things need to be explored.”
The big question therefore is whether efficiency improvements and the uptake of renewables will keep up with the accelerating growth in data communication, and its energy demands.
Global carbon emissions remained unchanged in 2014 from the previous year, giving hope that the link between economic growth and greenhouse gas emissions may have decoupled. The challenge is for the digital industry to do the same.

2017 Was the Most Expensive Year Ever for U.S. Natural Disaster Damage
Devastating natural disasters dominated last year’s headlines and made many wonder how the affected areas could ever recover. According to data from the U.S. National Oceanic and Atmospheric Administration (NOAA), the storms and other weather events that caused the destruction were extremely costly.
Specifically, the natural disasters recorded last year caused so much damage that the associated losses made 2017 the most expensive year on record in the 38-year history of keeping such data. The following are several reasons that 2017 made headlines for this notorious distinction.
Over a Dozen Events With Losses Totalling More Than $1 Billion Each
The NOAA reports that in total, the recorded losses equaled $306 billion, which is $90 billion more than the amount associated with 2005, the previous record holder. One of the primary reasons the dollar amount climbed so high last year is that 16 individual events cost more than $1 billion each.
Global Warming Contributed to Hurricane Harvey
Hurricane Harvey, one of two Category-4 hurricanes that made landfall in 2017, was a particularly expensive natural disaster. Nearly 800,000 people needed assistance after the storm. Hurricane Harvey alone cost $125 billion, with some estimates even higher than that. So far, the only hurricane more expensive than Harvey was Katrina.
Before Hurricane Harvey hit, scientists speculated climate change could make it worse. They discussed how rising ocean temperatures make hurricanes more intense, and warmer atmospheres have higher amounts of water vapor, causing larger rainfall totals.
Since then, a new study published in “Environmental Research Letters” confirmed climate change was indeed a factor that gave Hurricane Harvey more power. It found environmental conditions associated with global warming made the storm more severe and increase the likelihood of similar events.
That same study also compared today’s storms with ones from 1900. It found that compared to those earlier weather phenomena, Hurricane Harvey’s rainfall was 15 percent more intense and three times as likely to happen now versus in 1900.
Warming oceans are one of the contributing factors. Specifically, the ocean’s surface temperature associated with the region where Hurricane Harvey quickly transformed from a tropical storm into a Category 4 hurricane has become about 1 degree Fahrenheit warmer over the past few decades.
Michael Mann, a climatologist from Penn State University, believes that due to a relationship known as the Clausius-Clapeyron equation, there was about 3-5 percent more moisture in the air, which caused more rain. To complicate matters even more, global warming made sea levels rise by more than 6 inches in the Houston area over the past few decades. Mann also believes global warming caused the stationery summer weather patterns that made Hurricane Harvey stop moving and saturate the area with rain. Mann clarifies although global warming didn’t cause Hurricane Harvey as a whole, it exacerbated several factors of the storm.
Also, statistics collected by the Environmental Protection Agency (EPA) from 1901-2015 found the precipitation levels in the contiguous 48 states had gone up by 0.17 inches per decade. The EPA notes the increase is expected because rainfall totals tend to go up as the Earth’s surface temperatures rise and additional evaporation occurs.
The EPA’s measurements about surface temperature indicate for the same timespan mentioned above for precipitation, the temperatures have gotten 0.14 Fahrenheit hotter per decade. Also, although the global surface temperature went up by 0.15 Fahrenheit during the same period, the temperature rise has been faster in the United States compared to the rest of the world since the 1970s.
Severe Storms Cause a Loss of Productivity
Many people don’t immediately think of one important factor when discussing the aftermath of natural disasters: the adverse impact on productivity. Businesses and members of the workforce in Houston, Miami and other cities hit by Hurricanes Harvey and Irma suffered losses that may total between $150-200 billion when both damage and sacrificed productivity are accounted for, according to estimates from Moody’s Analytics.
Some workers who decide to leave their homes before storms arrive delay returning after the immediate danger has passed. As a result of their absences, a labor-force shortage may occur. News sources posted stories highlighting that the Houston area might not have enough construction workers to handle necessary rebuilding efforts after Hurricane Harvey.
It’s not hard to imagine the impact heavy storms could have on business operations. However, companies that offer goods to help people prepare for hurricanes and similar disasters often find the market wants what they provide. While watching the paths of current storms, people tend to recall storms that took place years ago and see them as reminders to get prepared for what could happen.
Longer and More Disastrous Wildfires Require More Resources to Fight
The wildfires that ripped through millions of acres in the western region of the United States this year also made substantial contributions to the 2017 disaster-related expenses. The U.S. Forest Service, which is within the U.S. Department of Agriculture, reported 2017 as its costliest year ever and saw total expenditures exceeding $2 billion.
The agency anticipates the costs will grow, especially when they take past data into account. In 1995, the U.S. Forest Service spent 16 percent of its annual budget for wildfire-fighting costs, but in 2015, the amount ballooned to 52 percent. The sheer number of wildfires last year didn’t help matters either. Between January 1 and November 24 last year, 54,858 fires broke out.
2017: Among the Three Hottest Years Recorded
People cause the majority of wildfires, but climate change acts as another notable contributor. In addition to affecting hurricane intensity, rising temperatures help fires spread and make them harder to extinguish.
Data collected by the National Interagency Fire Center and published by the EPA highlighted a correlation between the largest wildfires and the warmest years on record. The extent of damage caused by wildfires has gotten worse since the 1980s, but became particularly severe starting in 2000 during a period characterized by some of the warmest years the U.S. ever recorded.
Things haven’t changed for the better, either. In mid-December of 2017, the World Meteorological Organization released a statement announcing the year would likely end as one of the three warmest years ever recorded. A notable finding since the group looks at global land and ocean temperature, not just statistics associated with the United States.
Not all the most financially impactful weather events in 2017 were hurricanes and wildfires. Some of the other issues that cost over $1 billion included a hailstorm in Colorado, tornados in several regions of the U.S. and substantial flooding throughout Missouri and Arkansas.
Although numerous factors gave these natural disasters momentum, scientists know climate change was a defining force — a reality that should worry just about everyone.
How to be More eco-Responsible in 2018
Nowadays, more and more people are talking about being more eco-responsible. There is a constant growth of information regarding the importance of being aware of ecological issues and the methods of using eco-friendly necessities on daily basis.
Have you been considering becoming more eco-responsible after the New Year? If so, here are some useful tips that could help you make the difference in the following year:
1. Energy – produce it, save it
If you’re building a house or planning to expand your living space, think before deciding on the final square footage. Maybe you don’t really need that much space. Unnecessary square footage will force you to spend more building materials, but it will also result in having to use extra heating, air-conditioning, and electricity in it.
It’s even better if you seek professional help to reduce energy consumption. An energy audit can provide you some great piece of advice on how to save on your energy bills.
While buying appliances such as a refrigerator or a dishwasher, make sure they have “Energy Star” label on, as it means they are energy-efficient.
Regarding the production of energy, you can power your home with renewable energy. The most common way is to install rooftop solar panels. They can be used for producing electricity, as well as heat for the house. If powering the whole home is a big step for you, try with solar oven then – they trap the sunlight in order to heat food! Solar air conditioning is another interesting thing to try out – instead of providing you with heat, it cools your house!
2. Don’t be just another tourist
Think about the environment, as well your own enjoyment – try not to travel too far, as most forms of transport contribute to the climate change. Choose the most environmentally friendly means of transport that you can, as well as environmentally friendly accommodation. If you can go to a destination that is being recommended as an eco-travel destination – even better! Interesting countries such as Zambia, Vietnam or Nicaragua are among these destinations that are famous for its sustainability efforts.
3. Let your beauty be also eco-friendly
We all want to look beautiful. Unfortunately, sometimes (or very often) it comes with a price. Cruelty-free cosmetics are making its way on the world market but be careful with the labels – just because it says a product hasn’t been tested on animals, it doesn’t mean that some of the product’s ingredients haven’t been tested on some poor animal.
To be sure which companies definitely stay away from the cruel testing on animals, check PETA Bunny list of cosmetic companies just to make sure which ones are truly and completely cruelty-free.
It’s also important if a brand uses toxic ingredients. Brands such as Tata Harper Skincare or Dr Bronner’s use only organic ingredients and biodegradable packaging, as well as being cruelty-free. Of course, this list is longer, so you’ll have to do some online research.
4. Know thy recycling
People often make mistakes while wanting to do something good for the environment. For example, plastic grocery bags, take-out containers, paper coffee cups and shredded paper cannot be recycled in your curb for many reasons, so don’t throw them into recycling bins. The same applies to pizza boxes, household glass, ceramics, and pottery – whether they are contaminated by grease or difficult to recycle, they just can’t go through the usual recycling process.
People usually forget to do is to rinse plastic and metal containers – they always have some residue, so be thorough. Also, bottle caps are allowed, too, so don’t separate them from the bottles. However, yard waste isn’t recyclable, so any yard waste or junk you are unsure of – just contact rubbish removal services instead of piling it up in public containers or in your own yard.
5. Fashion can be both eco-friendly and cool
Believe it or not, there are actually places where you can buy clothes that are eco-friendly, sustainable, as well as ethical. And they look cool, too! Companies like Everlane are very transparent about where their clothes are manufactured and how the price is set. PACT is another great company that uses non-GMO, organic cotton and non-toxic dyes for their clothing, while simultaneously using renewable energy factories. Soko is a company that uses natural and recycled materials in making their clothes and jewelry.
All in all
The truth is – being eco-responsible can be done in many ways. There are tons of small things we could change when it comes to our habits that would make a positive influence on the environment. The point is to start doing research on things that can be done by every person and it can start with the only thing that person has the control of – their own household.
