Speech by the Prince of Orange during the seminar Energy Efficiency and Sustainability, on the occasion of the State Visit to Mexico

Your Excellencies, ladies and gentlemen,

First, I would like to thank all of you for participating in today's seminar. I would also like to extend a special word of thanks to our Mexican hosts. It is an honour to be here today. In a way, this seminar shows just how far we have come on our way to a new, low-carbon energy future. New technology, new partnerships, a truly global approach to the problem of climate change: this is what I see emerging. We have also measured - as far as we could - the distance we still have to go. Let's take encouragement from the fact that we are on this road together, and that we are indeed moving ahead. Energy efficiency is an issue that is particularly close to my heart. There are several reasons for that.

First of all, it is a subject that touches upon our daily lives. In order to be more energy-efficient, we must critically re-appraise how we live and the choices we make. Everybody needs to be aware of the extreme effects of climate change and the urgency with which we must deal with them. And everybody needs to be involved in finding sustainable solutions. This, I believe, is crucial to bringing about positive change: a low carbon economy should start at grass-roots level.

Second, energy efficiency is about our production methods. How we deal, or fail to deal, with our planet's mineral reserves. Precious natural resources merit careful treatment. We need to be in awe of nature, not see it as our right to abuse it. That is a basic starting point.

Mexican history can teach us a lesson here. As we now find ourselves in the one-time capital of the mighty Aztec empire, perhaps we can spend a few moments taking a closer look at the Aztecs, the true 'children of the sun'. Aztec culture is about respecting and revering nature. The famous Aztec pyramids of the sun and moon in Teotihuacan still attract thousands and thousands of tourists every year. The Queen, my wife and I look forward to visiting them on Friday. The Aztecs built their pyramids in order to pay tribute to their gods, the sun god in particular. Their message still rings true: we depend on nature, not the other way round. We depend on the sun as it is the one and only source of energy that makes our life on earth possible. Likewise, we depend on the unique atmosphere of this planet to protect us from the very harmful effects of that same sun. We have to stop this vital shield's gradual degradation.

Maybe the Aztecs were light-years ahead of us in realising that the sun is the only source of energy and that all other sources like fossil, hydro, wind or bio energy are mere derivatives. Maybe they were telling us to focus on the sun and to join forces in making solar energy so efficient that we can use it to solve all our energy requirements. Every 30 minutes the earth absorbs enough light to meet the world's energy needs for a year! Every 30 minutes! If only we could harvest it!

So while we are rightly looking for methods to reduce emissions in the short and medium term that have a distinct immediate effect on the pace of climate change, like Carbon Capture and Storage (CCS), we should never lose sight of the genuine long-term solutions to our energy problems. As I have already pointed out, our only source of energy is the sun. The rest are derivatives. So solar energy has the brightest future. And although it will take decades or even centuries before solar is our main source of energy, it is of the greatest importance to all future generations that we start conserving the best catchment areas, the world's deserts. Many regard deserts as a barren and hostile environment. In fact, they are a precious source of life, which we should embrace and protect for the common good. The circle of deserts surrounding the globe presents us with wonderful opportunities for both generating and transmitting solar energy.

Large-scale solar plants in deserts, connected to a cross-border or even intercontinental grid, are a fundamental solution for sustainable energy supplies after 2050. As an interesting side-effect - and of great benefit to the local population - heat from the power-generation process may be used to desalinate seawater or to generate cooling. So heat and water stress, now almost synonymous with deserts, can partly be solved, while mitigating the effects of climate change.

Although this solution may sound costly, scaling it up will make it a more profitable business than fossil energy. The point is, if we do not approach energy as a long-term investment, we will end up paying much higher bills.

So, ladies and gentlemen, we know the technology is there. Now we need the political will and the right approach to investment to achieve this fundamental transition towards a new energy system. Investments in sustainable solutions make our communities healthier, our planet cleaner, our economies stronger and our future brighter. Let us look beyond the current financial and economic crisis and build the foundations of a sustainable future. As a result of this crisis, billions of dollars of public spending are needed to bail out our economies and regenerate economic growth. If spent wisely on sustainable solutions, these investments will also contribute towards rescuing our planet. We owe this to our children and future generations.

The COP 15 conference which will be held in Copenhagen in December is the ideal opportunity to prove that we understand the urgency of the threats that face those future generations. The current generation is the only one that can help mitigate them. We have the knowledge and the means. Let us show the world we have the courage to take bold and necessary steps.

Let us make sure those future generations can be proud of us. Let us not go down in history as yet another generation that could have acted, but chose not to.

In a way, Mexico and the Netherlands are 'natural' partners in the field of energy. Mexico produces oil, the Netherlands produces gas, and we are both working towards a sustainable energy future. The Memorandum of Understanding which is about to be signed points the way ahead. We are guided by shared ambitions and work in the same spirit. Working together in a field as important as energy policy will benefit our two countries, as well as the world at large. We can and must make sure that the world acts together. Only then can Copenhagen be successful.

To make Copenhagen a success, we need drastic emission reductions, accepted by all nations. Do we achieve that through negative or positive strategies? Should we only focus on saying no or could we take a different approach? Should we allow everybody to emit as much as they want and then tax them so heavily under the 'polluter pays' principle that they make greater reductions collectively than through an approach that limits emissions? With those kind of financial incentives the private sector will gladly provide us with technologies that lead to huge emission reductions. I gladly leave it up to the delegates of COP 15 to make the right decisions and, if necessary, to finalize the treaty here in Mexico next year.

Let me conclude by giving you a Mexican proverb. "Cámaron que se duerme se lo lleva la chingada", or in English: "a shrimp that sleeps gets carried by the tide." Right now, strong currents are trying to pull us along, leading us to a future of energy scarcity, rising sea level and increasing pollution. Let's wake up, let's turn the tide and move in a different direction. Let's set an example to the rest of the world. I am sure that this seminar, with its plans, ideas and expertise on energy efficiency, will be a source of inspiration to all of you.

Thank you again for sharing your ideas with us. Thank you for being here.
