Renewable sources cannot cover more than 30% of our energy demand within the next 25 years. A clear-cut strategy for continued deployment of fossil energy sources is unavoidable in which fruitful competition and a level playing field for all commercial … Read more
In part 1 we have shown the potential of biomass. We will now deal with sun and water as sources of renewable energy. We will give an estimate of the maximum contribution of renewables. Solar and wind energy together could … Read more
After a few decades of research and development a halfway score is meaningful and, on headlines, very well feasible. For various reasons wind and biomass are showing their limits. Solar energy still has a big upward potential. Other sustainable sources … Read more
Corporate strategies are a shaky basis for getting society on a sustainable track. They may change, if other strategies would incur more profit. The green CEO may be replaced by a more traditional one. The company may be acquired by … Read more
Phosphorus is an essential element in the formation of vegetal and animal biomass. But whereas living organisms can use oxygen and nitrogen from the air for their processes, phosphorus is only available as a mineral, in the form of phosphate. … Read more
ILUC may have been nonexistent in 2000-2010 – the surprising result of our research at Biomass Research, using statistics that were not before analysed for this goal. Yes, farmers grew much more biofuel crops. But this was more than compensated … Read more
In the past few weeks, public discussion on shale gas in the Netherlands attained a new peak. Water utilities and brewers publicly favour a moratorium in view of risks for ground water supplies, and the Union of Chemical Industries asks … Read more

Many scientists from the molecular sciences, like chemists and biotechnologists, regard the use of biomass for energy production almost as a capital sin. It would be equal to burning down a top masterpiece. Many common citizens have a similar hang-up. … Read more
‘The unsuccessful energy transition stands in the way of the biobased economy,’ says Jan Rotmans. ‘Whereas the energy sector is going to disappear. In the future transition, the chemical sector will take its energy supply in its own hands. Above … Read more
I had looked forward intently to the report that Oxfam in the Netherlands (Oxfam Novib) would publish on 26 November, which would justify its campaign against European biofuel policies. They said, this would ‘conclude clearly’ that the economic and political … Read more
During advent, almost 50 tons of olivine sand will be dumped on stately Lange Voorhout in The Hague as a construction material for a crib. Olivine is a mineral rock which captures CO2. It would seem to be a ridiculous … Read more
Most posters against shale gas have disappeared from the streets and the municipal poster sites. Some cars still show them. But resistance has not faded away. Earlier articles on shale gas appeared on 12 July, 9 September, 17 September and … Read more
Diederik van der Hoeven appears to appreciate our moral position, but questions the practicality. But it is the practical consequences of the EU’s biofuel policy that prompted us to take a more radical stance on the current blending volumes. So … Read more
In two columns on this site I went into the food/fuel problem. Oxfam reacted to my first piece. But they did not answer some pressing questions. Therefore, once more the food/fuel problem and Oxfam’s position. This article appears as Oxfam … Read more
Recent food price increases have fuelled a new round in the food/fuel debate. They have had a major influence on EU policies, putting a halt to ambitious renewable fuel targets for 2020. But often, the arguments used in the food/fuel … Read more
One thing that I have learned in my NGO experience is that it is better to work on investment than on trade. If I would manage to convince a producer to make certain adjustments in their investment policy (environmental and … Read more
Oxfam working paper 161, entitled ‘The hunger grains’ has had a profound influence on the EU decision to scrap its stricter biofuels mandate for year 2020. But this influence is deplorable: the evidence presented in the report would lead to … Read more
‘By now, everyone knows about the phenomenon of Plastic Soup.’ So I am told ever more frequently nowadays. Yet, there are still a lot of people out there who have not heard of it. And even they often do not … Read more
Recently, newspapers and TV abound with reports on scientists who produce fuels like petrol and diesel oil from carbon dioxide and water. Sometimes with sensational headings like in The Independent, 19 October: ‘Exclusive: Pioneering scientists turn fresh air into petrol … Read more
