The content covers many of the possible applications of HAZOP and takes you through all the stages of a study. This simple, easily digestible book is a favorite in the chemical and process industries.

The second edition of a widely used textbook that explores energy resource options and technologies with a view toward achieving sustainability on local, national, and global scales.Human survival depends on a continuing supply of energy, but the need for ever-increasing amounts of it poses a dilemma: How can we find energy sources that are sustainable and ways to convert and utilize energy that are more efficient? This widely used textbook is designed for advanced undergraduate and graduate students as well as others who have an interest in exploring energy resource options and technologies with a view toward achieving sustainability on local, national, and global scales. It clearly presents the tradeoffs and uncertainties inherent in evaluating and choosing sound energy portfolios and provides a framework for assessing policy solutions.The second edition examines the broader aspects of energy use, including resource estimation, environmental effects, and economic evaluations; reviews the main energy sources of today and tomorrow, from fossil fuels and nuclear power to biomass, hydropower, and solar energy; treats energy carriers and energy storage, transmission, and distribution; addresses end-use patterns in the transportation, industrial, and building sectors; and considers synergistic complex systems. This new edition also offers updated statistical data and references; a new chapter on the complex interactions among energy, water, and land use; expanded coverage of renewable energy; and new color illustrations. Sustainable Energy addresses the challenges of making responsible energy choices for a more sustainable future.

Vi er håbløst afhængige af energi. Verdens energiforbrug stiger konstant, fordi energi holder sammen på verden, som vi kender den, og uden ville vores tilværelse være utænkelig. Vi har brug for energi til at skaffe mad, tøj og husly, til lys, varme, telefoner, computere, transport osv. Der er behov for nye energikilder, og de skal helst være grønne, hvis vi skal undgå en truende miljøkatastrofe. Derfor hylder regeringer og miljøforkæmpere de nye, grønne teknologier, og på verdensplan er der pumpet mange milliarder skattekroner i støtte til vedvarende energi.   Men en stor del af støtten går til projekter, der aldrig vil blive rentable. Forbrugerne betaler regningen, men hvem tjener egentlig på det – miljøet eller investorerne? Og hvad sker der med de stærkt forgældede projekter, når renten stiger? Eller når politikerne reducerer statsstøtten? Et sammenbrud inden for grøn energi kan sende nye chokbølger igennem verdensøkonomien og forsinke overgangen til bæredygtig forsyning med mange år.   Den grønne boble giver os et indblik i hvordan energisektoren hænger sammen: Hvilke forskellige energityper findes der? Hvad koster de, Hvor bæredygtige er de? Hvordan agerer investorer, regeringer og miljøforkæmpere i dette marked?   Det er nu, vi skal fortælle vores politikere, hvad de skal gøre for at garantere vores fremtidige energi. Grøn, bæredygtig energi er for Wimmer ensbetydende med, at det er private virksomheder, der producerer den. Virksomheder, der efter en begrænset periode kan stå på egne ben uden et hav af tilskud, skattefordele og indirekte backup-omkostninger. Derfor skal vi se den grønne boble i øjnene, så vi kan tage luften ud af boblen, før den brister.

I anledning af 100-året for Niels Bohrs atommodel, udgiver Forlaget Philosophia, i samarbejde med Niels Bohr Arkivet, et 4-binds værk af Bohrs filosofiske skrifter. Nu foreligger det første bind i serien, ”Atomteori og naturbeskrivelse”, der fokuserer på tanken om komplementaritet, som fundamentet i Bohrs filosofiske betragtninger.I dette bind er den tekst, hvori Bohr introducerer til tanken om komplementaritet – kernebegrebet i hans filosofiske refleksioner. I bogens indledning udfolder Bohr den filosofiske forståelsesramme, hvor komplementaritetsopfattelsen opstår.Bohr forklarer hvordan klassiske, filosofiske problemstillinger hænger sammen med de filosofiske overvejelser, der opstår i forbindelse med udviklingen og tolkningen af atomteori og kvantefysik. Han kommer bl.a. ind på forholdet mellem teori og praksis, anskuelse og tænkning.Bogen indeholder også en historisk gennemgang af atomteorien og kvantemekanikkens opståen og udformning.Indholdet i bogen er udvalgt af Niels Bohr selv. I mange år (1934-58) var det den eneste bog, som gjorde Bohrs filosofiske tanker alment tilgængelige – både i Danmark og resten af verden. Ofte blev disse tanker betegnet ”Københavnertolkningen af kvantemekanikken”.
