Solenergi

Vi ved det godt: Klimakrisen er tidens største politiske, sociale og økonomiske problem. Vores afhængighed af fossile brændsler risikerer reelt at blive menneskehedens endeligt. Vi skylder fremtidige generationer at sætte alt ind for at reducere udledningen af drivhusgasser. Lige nu. Men glem alt dette et øjeblik. Det grønne pengetræ er hverken en appel til din dårlige samvittighed eller dit varme hjerte. Bogens altoverskyggende argument er kynisk: Vi skal sætte tryk på den grønne omstilling, fordi der er gode penge at tjene på den. Vi skal erstatte det fossile med grønt, fordi det er en guldrandet forretning for danske virksomheder, almindelige lønmodtagere og din privatøkonomi.Igennem interviews med alt fra topchefer til havnearbejdere og atomfysikere, understreger Magnus Barsøe det imponerende potentiale inden for de grønne investeringer. Han kommer med politiske forslag, der kan sætte skub i den grønne omstilling og leverer en bredside til venstrefløjens vækstkritikere. Og han tager fat på et af de mest kontroversielle emner i klimadebatten: atomkraft.

This book looks at the success and continuing potential of photovoltaic (PV) technology in combating climate change by harnessing solar energy through building-integrated (BIPV) and building-applied photovoltaics (BAPV). With PV global capacity soaring from 940 GW in 2021 to 1100 GW in 2022 and projected to reach 1456 GW by the end of 2023, the world is witnessing an unprecedented shift towards renewable energy solutions. Today, no single country exists without some form of PV installation, driven by reduced costs and abundant free sunshine. The book¿s chapters delve into the advancements in PV technology, exploring its integration as an essential building material by examining 14 countries and regions ¿ Brazil, The Netherlands, Austria, Poland, Argentina, Iran, Germany, Malaysia, Oman, Bahrain, India, Australia, the United Kingdom, and Egypt ¿ and providing a comprehensive overview of their successful adoption of PV for electricity generation. Whether yoüre an architect, builder,engineer, or climate advocate, this vital resource offers insights, international case studies, and a path to a greener future.

Four main research and development paths are presented, the first two focusing on advancements in facade materials and Photovoltaic systems applicable to membrane architecture, the third referring to fog and dew harvesting and the fourth dealing with the future frontier of flexible transparency and designs for well-being through a passive solar system.

The tropical zones are dominated by developing countries, which mainly face problematic environmental issues. Different than four-season countries, tropical countries have a continuous summer-like season and therefore they are rich in clean energy sources like solar and biomass. Hence, the mitigations of environment and energy issues in the tropics would require specific understanding and different approach to solutions. This book offers an assortment of studies on scenarios of environment as well as energy demand and power generation technologies in the tropics. Many of the countries within the tropics are highly populated, and this results in various problems related to the environment and energy. The demand for energy in these countries keeps increasing but concurrently there are also environmental issues that require serious attention. As the global concern on the environment is alarming today, the choice of power generation should be of the cleanest possible resource. This various reports on research activities carried out in the tropics on the aspect of environment and energy presented in this book are highly beneficial for those who like to see an improvement in the tropics with regard to environment and energy systems.
