    1. Andrew, thank you for comment. It is known that the solar energy reaching to the planet is about 10,000 times greater than the needs of humanity. About a quarter of it goes to the evaporation of water and virtually always more or less evenly accumulates in the atmosphere at any point around the world. Since the annual precipitation is about 1 m of rainfall with an average height of 5 km, this gives a potential capacity of about 810 TW, which is more than 60 times greater than all the current needs of humanity (13 TW). Standard hydroelectricity can only use a small fraction of this energy, because all precipitation lose most of their potential energy on the way to the ground to overcome the resistance of the air and hit the ground. In order to use this potential energy more cost-conscious, it is necessary to collect the water at that altitude, where it condenses, and use all possible vertical hydraulic head. This is what constitutes the essence of the decision. All the best from CCRES.

  1. Small nations, renewable giants

    Renewable energy truly may be the phrase of the day, as Croatia too has pledged to reach a 20% share of energy produced from renewable sources by the year 2020.

    Uruguay gets 94.5% of its electricity from renewables. In addition to old hydropower plants, a hefty investment in wind, biomass and solar in recent years has raised the share of these sources in the total energy mix to 55%, compared with a global average of 12%, and about 20% in Europe.

    Costa Rica went a record 94 consecutive days earlier this year without using fossil fuel for electricity, thanks to a mix of about 78% hydropower, 12% geothermal and 10% wind. The government has set a target of 100% renewable energy by 2021. But transport remains dirty.

    Iceland has the advantage of being a nation of volcanoes, which has allowed it to tap geothermal sources of 85% of its heating and – with the assistance of hydropower – 100% of its electricity. This has made it the world’s largest green energy producer per capita.

    Paraguay has one huge hydropower dam at Itaipu, which supplies 90% of the country’s electricity.

    Lesotho gets 100% of its electricity from a cascade of dams that have enough spare capacity to export power to South Africa.

    Bhutan’s abundant hydropower resources generate a surplus of electricity that accounts for more than 40% of the country’s export earnings. But over-reliance on one source can be a problem. In the dry season, it has to import power from India.

    Croatia appears to be suffering, as we have written time and again, from the sort of overall investment climate which does leave more than a little to be desired. For instance, whilst researching for this article we have identified that, if one wishes to invest into wind or solar or any other renewable energy source for that matter, one must obtain no less than 62 different permits. The State, it is no secret, hasn’t the spunk any more to engage in infrastructural investment on a massive scale, which does mean, as we have stated in the introduction, that it will try to incentivise entrepreneurial activity, mainly by facilitating the absorption of eu funds allocated for that purpose. This naturally means that it is up to the private sector – principally the sme sector – to take the initiative, but with all that red tape still around…

    Yet again, we are forced to advocate patience. The newly proposed legislation, which is due to be passed by the Parliament by the end of this year will reduce the number of required permits to ‘just’ 21, and with State subsidies and eu funding readily available, it may just mean that the market is finally ripe for the picking. We, at least, prefer to believe that truly is the case…
