    Demand-Side Energy Management

    No full text
    Concerns about climate change, increasing energy prices and dependability of energy supply ask for drastic changes in the energy supply chain, but also in the current demand-supply philosophy. Current trends in energy consumptions result in an increasing and more fluctuating electricity usage, causing a decreas- ing efficiency of conventional power plants and increasing requirements on the grid and generation capacity. Furthermore, in order to meet the CO2 emission reductions aimed for in the 20-20-20 agreements, at least a large part of the electricity should be generated by renewable sources which are to a large extent uncontrollable. This introduces even more challenges to maintain a reliable, dependable and affordable electricity supply. Therefore, new ways 1) to achieve a more efficient use of the generated electricity of existing power plants, 2) to facilitate the large scale introduction of renewable sources and 3) to allow a large scale introduction of new technologies for consumption and storage of energy, is required, while maintaining grid stability and ensuring a reliable and affordable supply

    Radio frequency (RF) radiation exposure and health

    No full text
    Through the history of wireless communication I show the explosive growth in time of mobile telephony and explain how this affects the perception of fear of the general public for electromagnetic radiation. Then, after explaining the physics of electromagnetic radiation, I discuss the interaction with the human body. I explain how RF and microwave radiation cannot be directly carcinogenic. Then I discuss the heating effect of RF and microwave radiation and the exposure limits to prevent adverse health effects for humans. After explaining how a correlation between electromagnetic fields and electromagnetic hypersensitivity has not been established, I will discuss the probability and possibility of a causal relationship between long-term RF radiation exposure and cancer. I will discuss the viewpoint of the World Health Organization that considers RF radiation as possibly carcinogenic for humans and those of leading expert organizations and conclude with current and future epidemiologic research
