TL;DR: In this article, the development of wave energy utilization since the 1970s is discussed, with a focus on the characterization of the wave energy resource; theoretical background, with especial relevance to hydrodynamics of wave absorption and control; how a large range of devices kept being proposed and studied, and how such devices can be organized into classes; the conception, design, model-testing, construction and deployment into real sea of prototypes.
Abstract: Sea wave energy is being increasingly regarded in many countries as a major and promising resource. The paper deals with the development of wave energy utilization since the 1970s. Several topics are addressed: the characterization of the wave energy resource; theoretical background, with especial relevance to hydrodynamics of wave energy absorption and control; how a large range of devices kept being proposed and studied, and how such devices can be organized into classes; the conception, design, model-testing, construction and deployment into real sea of prototypes; and the development of specific equipment (air and water turbines, high-pressure hydraulics, linear electrical generators) and mooring systems.

TL;DR: In this paper, the technical and economic prospects for making fuels and electricity from renewable energy sources are assessed, including hydropower, wind energy, solar thermal electric technology, photovoltaic technology, ocean energy systems, geothermal energy, biomass conversion technology, and solar hydrogen.
Abstract: This book assesses the technical and economic prospects for making fuels and electricity from renewable energy sources. Twenty-three chapters discuss the following renewable technologies: hydropower; wind energy; solar thermal electric technology; photovoltaic technology (6 chapters); ocean energy systems; geothermal energy; biomass conversion technology (8 chapters); solar hydrogen; and utility strategies for using renewables. All chapters have been processed for inclusion on the data base.

TL;DR: Satellite altimeter data from Topex/Poseidon is used to map empirically the tidal energy dissipation and shows that approximately 1012 watts—that is, 1 TW, representing 25–30% of the total dissipation—occurs in the deep ocean, generally near areas of rough topography.
Abstract: How and where the ocean tides dissipate their energy are long-standing questions that have consequences ranging from the history of the Moon to the mixing of the oceans. Historically, the principal sink of tidal energy has been thought to be bottom friction in shallow seas. There has long been suggestive evidence, however, that tidal dissipation also occurs in the open ocean through the scattering by ocean-bottom topography of surface tides into internal waves, but estimates of the magnitude of this possible sink have varied widely. Here we use satellite altimeter data from Topex/Poseidon to map empirically the tidal energy dissipation. We show that approximately 10(12) watts--that is, 1 TW, representing 25-30% of the total dissipation--occurs in the deep ocean, generally near areas of rough topography. Of the estimated 2 TW of mixing energy required to maintain the large-scale thermohaline circulation of the ocean, one-half could therefore be provided by the tides, with the other half coming from action on the surface of the ocean.
