What will the history books say about Durban?

The Durban Summit is over, but the problems are still there. What remains clear after the arduous negotiations is that we are having a hard time working towards the future, making sacrifices for others, and being accountable for the environmental problems caused by generations of the recent past and that of our own.

In all likelihood, the Durban Summit (South Africa) will go down in history more as a UN success than a key step forward in the struggle against climate change. While some have described it as a “milestone”, certain environmentalist groups or countries like China have criticized the “lack of will” of developed countries. Continuation of the Kyoto Protocol has been under debate since 1995 at the different summits organized by the United Nations Framework Convention on Climate Change, and time after time they can clearly be summed up as being “a lot of talking the talk but little walking the walk”. Albeit with an uncertain fate, the Kyoto Protocol has been extended, but Canada, Japan, Russia and the U.S., which failed to ratify the protocol in 1997, have pulled out. No surprise there. The biggest polluters are therefore excluded, for the European Union and the nations that have signed up to extension of the protocol are responsible for only 15% of pollutant gas emissions. What has been established, however, is the institution of a roadmap, proposed by the EU, towards a legally binding deal by 2015 to cut emissions. In other words, it has been established to come to a decision in the future.

What will the history books say about Durban?

Nevertheless, Durban shall indeed go down in history for turning the city into the birthplace of the Green Climate Fund. This was an issue of great concern to developing nations. The fund will be allocated to help developing countries deal with natural disasters occurring as the result of climate change.

As far as forest protection is concerned, there are no new developments. Gaining momentum, therefore, is the idea of financing for forest protection coming from industrial power plants that would not have to drastically cut their emissions due to the absorption of carbon dioxide.

Those who always lose keep losing and those who do nothing continue to keep their arms folded. However, this is a game we all lose. CO2 emissions entail irreversible global consequences and make no distinctions between the guilty and the innocent. We all suffer the consequences.

There are plenty of reasons why Earth can no longer wait, and we need a legally binding agreement to compel all of us to preserve the world left to us by our predecessors. The only way for us to “save tomorrow today” is to lower emissions through less-contaminating energy generation, promote responsible energy use, make use of the energy sources provided by our planet, and make ourselves aware of the need for immediate change. Political will and awareness must go hand in hand with Qatar in 2015 or we shall once again see a clear example of how our planet continues to suffer while we argue. Imperative, above all, is political will, for Science, with a capital S, has said everything it has to say on the matter.

The Fight against Desertification

As already discussed in previous articles, the main alternative sources of water are desalination, reuse of wastewater and recovery of contaminated aquifers. These new water sources are potentially of sufficient quality for many different uses, ranging from human consumption to industrial and agricultural processes, thereby helping on many fronts to develop the populations living in areas suffering from desertification.

In the agricultural and rural development sectors, we need to weigh up agro-environmental measures that will enable us to prevent and mitigate processes of land degradation, including incentives to encourage the forestation of marginal areas not suitable for agricultural uses.

In the forestry sector, we urgently need to restore plant cover, manage our forests sustainably, combat fires and roll out actions to defend and protect woodland.

Furthermore, proper management of water resources is pivotal in the fight against desertification. The arrival of new water resources that help prevent the over-exploitation of natural resources is a guarantee of success for the preceding measures. Similarly, rolling out the measures needed to recover over-exploited or contaminated aquifers, coupled with the creation of new resources, will certainly help in the fight against desertification by fostering the recovery of existing natural resources and helping to maintain populations and use of farming land.

Combating desertification, one of the many adverse phenomena undermining local development and plaguing many regions around the world, is essential to ensuring the genuinely sustainable development of arid and semi-arid land and preventing migration and increased pressure on other areas, and also requires proper management of agricultural and water resources.

This daunting task must be a global commitment to be undertaken by institutions and the population as a whole, and requires coordinated leadership among countries. What other measures do you consider appropriate?

Desertification, an overlooked Threat

Desertification is essentially land degradation, an undesirable effect that leads to a drop in, or disappearance of biological or economic productivity on dry and irrigated agricultural land, pastures and grazing land, and forests and woodland in arid, semi-arid and sub-humid lands. The primary underlying cause is poor human management and climate change, mainly drought.

It is a complex phenomenon in which numerous intertwined factors all play a role. As confirmed by the UN Food and Agriculture Organization (FAO) in a document signed by over one hundred countries against the backdrop of the United Nations Convention to Combat Desertification (UNCCD), desertification arises “because dryland ecosystems, which cover over one third of the world’s land area, are extremely vulnerable to over-exploitation and inappropriate land use”.

Combating the existing situation requires a raft of different measures and structural reforms. Let us not forget that every year, a land area larger than Belgium or Rwanda falls prey to desertification. At present, this phenomenon affects roughly 40% of our planet’s land mass, including certain parts of Europe. 70% of all dryland suffers from desertification, representing a land area of 36 million kilometres.

All in all, over 250 million people suffer the direct effects of desertification, a problem that also affects over one billion people from over a hundred different poor nations.

Tackling desertification is crucial to ensuring the sustainability of inhabited drylands. We cannot continue to overlook the fact that land provides the natural foundations for human life and social development. To solve this mammoth problem, we need to roll out immediately, and in tandem, a raft of different measures within the agricultural and forestry sectors, while improving our management of water resources. For this we need the committed support of institutions and governments from around the world. Desertification is a problem that affects all of us and drags down income by an estimated 42 billion dollars in those zones directly affected by desertification alone.

In subsequent articles, I intend to analyse and explain the measures recommended by international bodies to tackle this phenomenon, while providing some examples of possible alternatives.

The Carbon Economy

In order to meet the energy challenges we face, we need to drive forward a new energy paradigm based on the use of renewable energies. Clean air is a global public good by design, and as such, “market” mechanisms do not easily take into account the deterioration of this resource. Generally speaking, people have a tendency to fail to bear in mind the third-party harm derived from damage to the environment in conducting their activities.

For this reason, conserving both our way of life and the environment requires the establishment of regulatory mechanisms that include the cost of its social and environmental impact in the price of energy so that all kinds of energy can compete on a level playing field. Following the implementation of this new economic paradigm, the change in incentives will give rise to a new model, that of the carbon economy, which will lead to exponential technological development of renewables, achieving a drastic reduction in pollution and in the political and economic dependence acquired from a handful of unstable countries that today control the world’s oil, thereby enabling planet Earth to continue to bear its fragile load of living beings for eons to come.

Green Jobs

Ample evidence and a multitude of analyses show that “green industries”, including renewable energy production, have the capacity to boost economic recovery, while contributing at the same time to solving the problems of fossil energy depletion and climate change. Given the economic and social need entailed, job creation is one of the biggest concerns for governments, public administration, and citizens alike. In this sense, creating millions of green jobs will not only help to protect the environment, but will also offer meaningful work to those who are out of a job, promoting social welfare and justice and favoring a balanced distribution of wealth.

Empleos verdesA representative fact: the renewable energy sector, which accounts for less than five percent of global primary energy production, today employs the same number of people as the entire oil and gas industry worldwide. According to the “Working for the Climate” report, the renewable energy industry has the potential to provide employment for nearly seven million people by 2030, creating three new green positions for each of today’s fossil-linked jobs.

In order to make the most of the tremendous opportunity renewable energies afford, governments of both developed and developing countries need to implement policies aimed at achieving innovative progress and training in all renewable energy-related areas. Deeply engaged policy and practice can help turn this sector into a major source of employment, enabling us to overcome the present economic situation and definitively set third-world economies in motion.

Given the growth in population over the last fifty years, the critical environmental situation, and existing social awareness, it is safe to say that the world we live in today is very different from that of our parents. We have an opportunity and we have the technology, and now we need the vision and courage to take decisive action today to transform our energy model in order to ensure that our children and grandchildren may fully enjoy the world we leave behind.

Diversification for the electric sector

Planta termosolar

For the electric sector, the possibility of generating all of the electricity consumed worldwide through renewables is a long-term proposition.  However, in the short term, existing dependence on fossil fuels is still extremely high, and in the technological realm, there remain areas to be researched and developed.

Our renewable future must be based on a balanced model that integrates the different kinds of clean energy sources while taking the particular features of each type into account. For example, we need to take into consideration how well solar and wind power complement each other; the former can be employed to focus on day-time production, with the latter centering on production during the night time. The energy required to meet demand peaks could be obtained by using solar concentrating power technology with storage capability and biomass.

Sooner or later, we will have to take a step forward, contributing solutions instead of talking about the problems. Will we be ready when the time comes?

Biofuels for transportation

Biomasa

In the case of transportation, the solution to lowering emissions and economic dependence on oil-producing countries lies in the use of biofuels. Producers are making significant innovative efforts in order to be able to combine the traditional engine with other renewable technologies, including solar-powered hybrids, hydrogen engines, and electric cars.

Biofuels are a clean substitute for both gasoline and diesel fuel. Estimates show that global CO2 emissions in the transportation sector will exceed 8.5 billion tons by 2030. And the European Union foresees a rise in continental emission levels of between 970.6 million and 1.261 billion tons per annum between 2000 and 2030. Given this scenario, biofuels naturally constitute the most promising alternative for lowering the environmental impact of this sector. Biofuels, moreover, will most likely help to make hydrogen, after electricity, the second most prominent energy vector.

The necessary resources are undoubtedly available to us, but are we ready for a change in mentality?

The energy that keeps the world moving

Energy is the cornerstone to proper working order, development, growth, and well-being of all industrialized societies. And as societies progress, their expenditure on energy sources and materials goes up. In Spain, for example, primary energy consumption increased by 95% between 1980 and 2002 as a result of the nation’s development, manifested in the rise in the country’s vehicle fleet in the transportation sector, the number of energy-consuming systems and equipment, air conditioning systems in residential and tertiary-sector construction, and street lighting. Is our energy supply secure for the future? Is energy production compatible with conservation of the environment? Can Public Administration and citizens do anything to lower energy consumption?

By the end of the 21st century, energy use is expected to be 2.5 times higher than today’s figures, accompanied by the ensuing rise in greenhouse gas (GHG) emissions (pdf). Estimates show that achieving a GHG emissions reduction of around 20 percent (assuming that the current electrical power generation pattern holds), would require generating between 40 and 50 percent of our energy from clean and renewable sources. Making it possible for our world to meet its power demand exclusively from renewable energies (those obtained from virtually endless natural resources, including solar power, wind power, hydraulic power, biomass, geothermal and ocean power) is a reality dependent on three key factors: the degree of awareness shown by our society and leaders regarding the consequences of climate change and the environmental deterioration of the planet, growing scarcity (and the subsequent rise in price) of fossil fuels in the coming years, and the strategic importance for countries to gain energy independence in order to ensure their energy supply (when faced with crises such as the case of Iraq or Libya, for example).

Activities associated with energy production, processing, transformation, and consumption today account for over 60 percent of the world’s greenhouse gas emissions, and, therefore, in order to halt climate change the development of clean energies is crucial in achieving an emissions reduction in the energy sector. At the same time, the exhaustion of the fossil-based model will give rise to a significant increase in its cost. A report to this effect, published recently by the International Energy Agency (IEA), emphasized that the price of a barrel of crude oil will climb to 200 dollars by 2030.

What price are we willing to pay until we consider other options?

Potential measures for achieving higher energy efficiency

Within the context in which over 80% of the energy consumed in Spain comes from fossil sources, and one in which 77% has to be imported from foreign countries, many of which, as we have pointed out, are politically and socially unstable, it is imperative that we promote measures geared towards reducing energy consumption together with the steps already mentioned to boost diversified domestic production of clean energies.

Among the subgroups of potential measures for achieving higher energy efficiency and independence, the commitment to innovation may be the safest option in the long term, particularly in the following areas:

  • Power electronics and microelectronics to enable manufacturing of more efficient equipment and systems. For example, the development of new low-consumption lighting systems with a lower environmental impact, increased light intensity and a longer useful life, which could lead to energy savings of 90 percent.
  • Energy storage systems. In the electrical system, they would absorb consumption peaks by releasing stored energy at times of maximum consumption, which would give rise to fuel savings at the point of generation. In the transportation segment, such systems would enable recovery of a large portion of the energy from vehicle braking, in order to store and subsequently release it in situations involving ignition or peak power demand.
  • New air-conditioning (central or individual) techniques to considerably lower energy demand. Furthermore, the development of self-sufficient buildings would enable a reduction in the amount of energy required from the power grid and thereby lead to energy savings by eliminating losses in distribution, transmission, and generation.
  • New materials for application to building construction (semi-transparent electrochromic materials, enabling direct management of the radiation penetrating building structures), transportation (lightweight resistant materials yielding lower vehicle weight) or consumption (semiconductor nanomaterials such as graphene would enable the development of smaller electronic devices that use less energy).
  • Additionally, new sources of energy for industrial process, electricity generation, and transportation. Noteworthy in this area is hydrogen production from renewable sources, through biofuel reforming, fermentation of vegetable matter, or the use of innovative water hydrolysis mechanisms to enable direct production upon demand.

Oferta y demanda de hidrógenoInnovation plays a key role in today’s scenario, which urgently needs a reduction in energy use, not only to pursue new technological solutions, but also to ascertain the limitations of existing solutions and determine the steps to take in favor of energy savings and efficiency. Innovation in energy efficiency offers both direct benefits, through energy resource savings and by lowering foreign dependence, as well as the indirect benefits of environmental enhancement. Moreover, higher energy efficiency in a scenario of sustained economic growth also helps to create jobs and increase competitiveness in industries for which energy constitutes a key factor in production processes. Innovation, coupled with citizens’ awareness of responsible energy use, should therefore pave the way towards energy sustainability.

Energy Efficiency: Putting the Brakes on Waste?

Energy savingEnergy is the cornerstone to proper working order, development, growth, and well-being of all industrialized societies. And as societies progress,their expenditure on energy sources and materials goes up. In Spain, for example, primary energy consumption increased by 95% between 1980 and 2002 as a result of the nation’s development, manifested in the rise in the country’s vehicle fleet in the transportation sector, the number of energy-consuming systems and equipment, air conditioning systems in residential and tertiary-sector construction, and street lighting.

The Spanish government has proposed a package of measures (pdf) aimed at increasing energy efficiency in three major areas: transportation and mobility, building and construction, and lighting and electricity consumption. The steps approved are anticipated to yield an estimated savings of 28.6 million barrels of oil and 2.3 billion euros per annum in energy imports, thereby cutting annual CO2 emissions by 12.5 million tons.

Given a context in which over 80% of the energy used in Spain comes from fossil sources (pdf), and where 77% of the nation’s energy has to be imported from foreign countries(pdf), many of which are politically and socially unstable, it is essential to bolster the nation’s energy independence and security while ensuring minimal environmental impact. Doing so therefore requires the promotion of measures aimed at lowering energy consumption in conjunction with other steps to boost diversified domestic production of clean energies, including solar thermal power and bioethanol. This is the only way to make the dream of humanity’s sustained progress come true.
