Heather Britton: India’s Energy-Climate Dilemma

Heather Britton is one of our new writers, today reporting on a summary of this paper by Andrew J Apostoli and William A Gough, covering the difficulties of pursuing reduced greenhouse gas emissions whilst fuelling one of the largest populations on the planet – India. The actions of this country are contributing to the eventual achievement of UN Sustainable Development Goals 7 and 13 – Affordable and Clean Energy, and Climate Action respectively.

India makes up 18% of the world’s population (1.2 billion people) with this value predicted to rise to 1.5 billion by 2030. Like many countries in the Global South, India is currently reliant upon fossil fuels to meet its energy demands, but it lacks the natural resources to provide energy for its people in this way – already 80% of its oil is imported, and this is likely to increase in the coming years. On top of this, India’s current energy production is falling short of their present requirements, with only 44% of households having access to electricity and 600,000 villages yet to be connected to the national electricity network.

You could be forgiven for thinking, therefore, that reducing carbon emissions would not be a priority, with the more pressing issue of making sure all Indians have access to energy taking precedence. This, however, is far from the reality, and although per-capita emissions are predicted to increase significantly as a result of the demands of a growing population, India’s renewable energy sector is ranked fifth in the world (Figure 1), and plans are in place to ensure that this sector’s growth does not stop here.

Although a factor in this statistic is the huge (and expanding) population of the country, it seems that India truly are passionate about pursuing a sustainable future. A survey recently revealed that many Indian citizens were happy to pay a carbon tax due to their awareness of the environment and the problems it is currently facing. To some, the environmental conscience of the country is seen as exacerbating India’s energy problem – if India can’t generate enough energy to ensure that all of its people have access to a sizeable and dependable energy source, why restrict the use of some of the most reliable methods of energy generation on the planet? – Others however have seen it as an admirable step in pursuit of sustainable development.

India has adopted ambitious targets to reduce greenhouse gas emissions through climate change policies and financial incentives to promote the development of new renewable energy initiatives, but it is currently unclear whether this will be enough for India to overcome its present day energy difficulties and meet the environmental promises that they have made both to their public and the global community (e.g. pledging to reduce emissions by 20-25% by 2020, although this is not legally binding).

The landscape and climate of India are well suited to many forms of renewable energy generation, making these options financially viable. It is clear that if India is to achieve its goal of supplying affordable energy to allow economic growth in an environmentally-conscious manner, renewable energy must be heavily invested in, enabling technological developments to be made in this industry.

The Indian government has produced a number of funding initiatives to encourage such investment: for example the ‘National Action Plan on Climate Change’ (NAPCC) was formed ‘to make India a prosperous and efficient economy that is self-sustaining for both present and future generations while confronting climate change’ (Apostoli and Gough, 2016). Its aims include reducing poverty, reducing the anthropogenic effects of climate change and developing technologies at a fast pace to ensure the regulation and mitigation of greenhouse gases.

Other funding initiatives include the coal tax, which has risen form 50 rupees per tonne of coal in 2010 to 400 rupees per tonne in 2016, the money from which is used to finance the national clean environment fund. Up to 2015 this fund had developed 46 clean energy initiatives, and has allowed further projects to take off since. In addition, tax-free bonds were offered from 2015-2016 for the financing of renewable energy initiatives, valued at around $800 million.

India therefore has succeeded in creating motivation for the development of renewable energy and has a plethora of methods of renewable energy generation available – the details for some of which I have outlined below:

Hydropower: With altitudes ranging from the highs of the Himalayas to lows of the Ganges delta, India’s landscape is perfectly suited to both large and small scale hydropower plants. As of 2013 17%  of the total electricity generated in India was from hydropower stations, second only to coal, demonstrating the potential for the development of this field in the future.

Solar: Sitting between the tropic of cancer and the equator, India is ideally situated for the generation of energy through the use of solar cells. Solar energy has the potential to surpass India’s annual energy consumption and allow it to become a global leader in solar energy, although the initial costs of the solar cells required is considerable. With schemes such as the ‘National Solar Mission’, aiming to have 22 GW of solar capacity by 2022, the solar sector in India is expected to expand rapidly.

Wind: There is huge potential for the wind industry. Wind generation is not only the largest growing renewable energy sector in India, but is also experiencing a recent rise in social acceptability, leading to the prediction that in 2020 wind energy will save 48 million tonnes of CO2.

Biomass: This is an incredibly important energy source for India, as 70% of the country’s population rely on it for energy. Currently, however, biomass is being used inefficiently, exposing children and women to high levels of indoor pollution. Policies have been developed to encourage more efficient and cleaner utilisation of this abundant fuel, but there is still a long way to go in improving the use of biomass.

The progress in the renewable energy industry sounds promising, but as ever problems are arising. Last year the Indian state Tamil Nadu generated more energy using solar cells than it required – but this energy could not be passed on to other states as the grid was not sophisticated enough to  connect this excess of renewable energy to neighbouring states. It is clear that developing methods of renewable energy generation is of great importance, but without careful planning much of the future renewable energy generated may go to waste.

In conclusion, sustainable development is of pressing concern to India, a country which houses a significant proportion of the world’s poor. There is currently heavy demand for fossil fuels, as the country undergoes unprecedented economic growth, rapid population increase and industrialisation. This places pressure not only on the national grid, but on unsustainable resources which will be exhausted under current consumption rates.

In response to these challenges India has invested heavily in the deployment of renewable energy strategies. With a combination of financial incentives, taxes and subsidies, India has caused a surge in renewable energy schemes, working to exploit the country’s landscape. Although it is still in the early stages of development, India’s dedication towards renewable energy will result in greater energy security for the world’s second largest population, providing them with the independence to facilitate economic growth whilst reducing their greenhouse gas emissions. There is certainly more work to be done, but the impetus that India has demonstrated in finding solutions to their energy crisis will hopefully result in a happy ending for this sustainable development story.

Introducing Our New Authors (3) – Jesse Zondervan

We’ve been introducing you to a couple of new faces on the GfGD blog, bringing fresh ideas and perspectives on topics relating to geoscience and sustainable development. We’re delighted to have their input, and look forward to their posts. Today we interview Jesse Zondervan.

I’m Jesse Zondervan, a PhD student at Plymouth freshly arrived from Imperial College in London and I hope to use the science communication experience I have to contribute to GfGDs exciting vision.

What is your academic background?

I have just started a new PhD project at Plymouth University and graduated from Imperial College in London.

I’m looking at Quaternary river system development in the High Atlas of Morocco together with my supervisors in Plymouth with support from Ibn Zohr University (Agadir, Morocco).

I got inspired to do this project through the work I did for my MSci research project. Here I worked towards understanding how rivers erode and shape the landscape, which we surprisingly can’t model very accurately yet. Since what goes on at the surface of our planet is largely dictated by forces directly or indirectly connected to rivers, it is important that we can understand fluvial processes quantitatively.

Connecting my research to development, I will mention that I recently went to Morocco to see the river systems I will be working on. I couldn’t help but notice how people interact with geological hazards in some of the poorest areas in Morocco. I am sure that I will see more as I do field work in Morocco over the next three years.

What experiences do you have of science communication and why do you think it is important?

My first contact with science communication was before I started my degree. In fact it’s the reason why I chose to do geology, so I’m aware of the impact science communication can make on young student’s career choices.

Over the years of my degree in London and Australia I maintained an interest in communicating science myself. I worked with a science marketing team and joined the editorial board of a science communication blog aggregator, ScienceSeeker. I’ve also got a video on YouTube and I’ve been working on a podcast for a while.

I believe science communication is important for two main reasons: inspire and direct people in their research careers & help academics maintain a fresh perspective on the research they do by communicating in a non-academic way (as I reflected on in my post Why communicating science is beneficial to everyone’s mental health).

How did you come across GfGD and why do you want to engage in our work?

Through my local university GfGD group I heard about Geology for Global Development. I did not get involved in their activities during my undergraduate, but as I started to think about my career after graduating, I became more interested in their work.

Over the years studying in London and Australia I accumulated quite a few friends who are involved in UN work or international development in general. Inspired by my friends, I started looking towards GfGD to guide me in making an impact while using my expertise and research work.

In 2015, the UN Millennium Development Goals and Sustainable Development tracks merged to form the 2030 Agenda launched in New York. I believe the UN 2030 agenda and its 17 Sustainable Development Goals present a change in the way policy recognizes the importance of working towards a sustainable future to achieve development goals, for all countries including the first world.

The new UN agenda creates an exciting new time in which geoscientists may be encouraged to work towards international development goals and receive more publicity and funding for research that contributes to understanding the way to sustainable development.

GfGD is one of the main pioneers in research on the intersection between geoscience and international development and promoting this new theme to the geoscience community.

The shifting of policy in development together with GfGD’s vision mean GfGD is well positioned to direct future research, which is what excites me about GfGD.

What themes and topics are you interested in and may be likely to write about in the future?

Since I do research in surface processes and tectonics, I am most easily interested by Disaster Risk Reduction (DRR) and hydrogeology (groundwater) topics.

I would like to learn more about the institutions which are involved in geoscience for international development. I will be collecting regular round-ups of blogging and news items about geology for global development topics.

As I’ve got an interest in making videos and podcasts, I would also love to work towards producing these for GfGD. If you have experience with this and would like to get involved contact me!

Plans for the future?

I would like to see how I can direct my research towards sustainable development relevance or to contribute to future research projects. I could see myself working for a Geological Survey (e.g., BGS) or as an academic affiliate to institutes like the Sustainable Earth Institute at Plymouth or the Earth Institute in New York.

I look forward to getting more involved in GfGD. Thank you for following our blog and I hope to bring you more content soon!

Wearing the Earth Down: The Environmental Cost of Fashion

Public Domain (

Eloise Hunt is an Earth science student at Imperial College London, and coordinator of the GfGD University group there. Today we publish her first guest article for the GfGD blog, exploring the environmental cost of fashion.

When we think of pollution, we imagine raw sewage pumped into rivers, open-cast mines or oil spills. We don’t often think of our inconspicuous white shirt or new jeans.  But, the overall impact that the fashion industry has on our planet is shocking.  The production of clothing has been estimated to account for 10% of total carbon impact. The fashion industry has been argued to be “one of the greatest polluters in the world, second only to oil“, although there is a lack of data to verify this.

Following London Fashion Week 2017, I wanted to take this opportunity to reflect on the environmental impacts of the fashion industry. Whilst geoscience may not seem to link to fashion, once you look closer at the production and environmental costs of textiles, you can see they are coupled with situations where geoscientists may be involved. Geoscience alone cannot improve the world.  But, through collaborations between geoscientists, engineers and policy makers, real changes can take place.

The lack of sustainability in fashion can be blamed on four major factors.  Firstly, there is enormous energy consumption associated with clothing.  Production is concentrated in countries such as Bangladesh and China. Factories are powered by coal before garments are shipped to the rest of the world.  It is difficult to find reliable data on how much fuel is used to transport clothes.  Yet, we do know that in the US only 2% of clothing is domestically produced and globally 90% of fabrics are transported by cargo ship  (read more).  One of these ships can produce as much atmospheric pollution as 50 million cars in just one year.

Another major factor is cheap synthetic fibres increasingly replacing natural cotton or wool. Polyester and nylon are both synthetic, non-biodegradable, energy intensive and made from petrochemicals.  Polyester is rapidly increasing in value and is now in over half of all clothing. Nylon is absorbent and breathable making it a popular choice for sportswear manufacturers.  But, nylon production forms nitrous oxide, a greenhouse gas 310 times more potent than carbon dioxide. Viscose is another synthetic fibre which is derived from wood pulp; the material’s popularity in fashion has caused deforestation in Brazil and Indonesia.  These countries are home to rainforests, often described as the ‘lungs of the earth’, acting as our most effective carbon sink and oxygen source.

Even stepping away from synthetics, cotton is hardly innocent.  It is incredibly water intensive accounting for 2.6% of global water use. It takes 2,700 litres of water to produce the average cotton t-shirt. Furthermore, 99.3% of cotton growth uses fertilisers, which can cause runoff and eutrophication of waterways.  Uzbekistan, the 6th largest producer of cotton in the world, is an important example of ‘cotton catastrophe’.  In the 1950s, two rivers were diverted from the Aral Sea as a source of irrigation for cotton production.  As the sea dried up, it also became over-salinated and laden with fertiliser and pesticides as a result of agricultural runoff. Contaminated dust from the desiccated lake-bed saturated the air, creating a public health crisis with some studies linking this to abnormally high cancer rates. Groundwater up to 150 m deep has been polluted with pesticides and regional climate has become more extreme with colder winters and hotter summers.  Currently, water levels in the Aral are less than 10% of what they were 50 years ago (Fig. 1). Whilst this is a dramatic example of cotton farming, environmental problems have  occurred in other locations.

The final environmental issue with fashion is responsible consumption and production (SDG 11).  Water problems in cotton producing areas cannot be fixed without consumers being held responsible for ecological impacts in the producing areas.  Globally, 44% of water used for cotton growth and processing goes towards exports.  High demand produces 150 billion items of clothing annually, which equates to 20 new items per person every year. Then, on average, each garment is worn only 7 times before being dumped in landfill.  In the UK alone, £30 billion worth of clothing is buried unused in our closets.

Faced with issues of energy consumption, the rise of synthetics, water consumption and fast fashion, it’s easy to feel powerless but with increased scrutiny come sustainable solutions. The UK James Dyson Award was recently bestowed upon the student inventor of Petit Pli, innovative children’s clothing with pleats which allows it to grow with children from four months to three years old (Fig. 2).  This could help tackle clothes waste and is a small yet significant thread of hope.  On an individual level, when you need new clothes opting for Fair Trade or organic fabrics is a simple way to minimise pesticide pollution and, in the case of cotton, reduce water consumption. Or, better yet choose second hand, vintage or upcycled items to prevent processing of more virgin fibres.

Fashion is not yet sustainable. We as consumers hold enormous power to persuade brands to make products that are clean, of high-quality and worth wearing.  People need to be taking fashion more seriously, not less.

Introducing Our New Authors (2) – Heather Britton

Exploring Zhangjiajie National Park, Hunan province, China

We’ve been introducing you to a couple of new faces on the GfGD blog, bringing fresh ideas and perspectives on topics relating to geoscience and sustainable development. We’re delighted to have their input, and look forward to their posts. Today we interview Heather Britton – a recent graduate of the University of Cambridge (UK). 

Tell us a bit about yourself.

I’ve recently graduated with a Master’s in Earth Sciences and have just returned from a summer of travelling around China. Like many graduating geoscientists, I’d like to do work that has a positive impact on the world and GfGD has helped to show me how I might be able to do that. I am looking forward to getting more involved with the charity through these blog posts and hope not only to enlighten others, but to learn myself about the interface between geoscience and international development.

I love spending time outdoors – I enjoy hiking and play rugby regularly. I also travel as much as I can; I have been accused by family of only studying Earth Sciences for the travel opportunities it brings, but in truth this is just one of the many perks of studying this versatile subject.

How did you become involved with GfGD?

I attended the Geology for Global Development annual conference last year, and was really inspired by the talks, poster session and discussions held there. If anyone is hesitant as to whether or they not they should attend, I highly recommend it [editor: details of 2017 event can be found here!]. The conference demonstrated to me that it was not only possible to have an ethical career using my degree in Earth Sciences but that it is crucial for the geosciences to be considered when undertaking development projects. From there I took a greater interest in international development and the involvement that the geosciences could have. I wanted to get more involved in the work of GfGD, so when I saw their call for volunteers I was quick to sign up and here I am.

What did you do in your Master’s?

In my final year I specialised in climate science, palaeontology and some petrology, although I find the whole spectrum of Earth Sciences interesting and you can expect my posts to cover a wide range of geoscience fields.

My research project was palaeontology based and I confess not particularly development related! The aim of the project was to calculate the lifespan of ammonites from the growth lines on their aptychi (calcitic plates thought to either be the lower jaw structure or opercula of certain species of ammonite). On top of this I looked into the palaeobiology and palaeoecology of ammonites, using oxygen isotopes to estimate the temperature of the water in which these organisms once lived. I enjoyed the research and am considering doing a PhD in the future.

What can we expect your blogs to cover?

I hope to cover a wide range of topics so that I can appeal to the interests of as many people as possible. I am also looking forward to summarising papers covering the geosciences and international development and connecting these with the UN Sustainable Development goals which underpin so much of the work that GfGD does.

An example of an issue I have been reading about recently is sustainable coral reef management and how developing communities can benefit from the sustainable use of the resources that these environments have to offer, for example through tourism. Regional co-operations are popping up in highly affected areas working to protect reef environments but there is still a lot of work to be done to preserve these unique and hugely biodiverse environments and make local people aware of what does and does not damage these sensitive ecosystems. I also have an interest in how best to make vulnerable communities more resilient to disasters, be they earthquakes, tsunamis or hurricanes like those that have been in the headlines these past few weeks.

Plans for the future?

My dream job would be using my knowledge of geoscience in an ethical way to make a positive difference to the world, whilst involving a lot of travel. For now, however, I am more than happy to invest time in writing blogs for this fantastic charity – it is certainly a step in the right direction.
