In fact, according to the US Energy Information Administration (EIA), the annual energy potential from waves off the Atlantic and Pacific coasts of the United States could be as much as 2,640 terawatt-hours (TWh)—a unit of measurement equivalent to outputting one trillion watts for one hour...
Plastic waste constitutes at least 85 percent of all trash floating in the world's oceans. The main problem with plastic — besides there being so much of it — is that it doesn't biodegrade. No natural process can break it down. (Experts point out that the durability that makes plas...
significantly untapped renewable energy source also exists: the world's oceans. The ocean is a vast repository of energy that can be derived from its motion. temperature, and chemistry. In fact, it is estimated that harnessing just 2 one-thousandths of...
Observational run-up height estimates of the incident wave of ancient tsunamis are inferred from the location of high-energy sedimentary deposits that can be traced inland or between raised lakes (e.g. Bondevik et al., 2005). Such estimates are generally underestimated as this is the minimum ru...
While it's true that the production of elastane fabrics requires high levels of energy and the use of a variety of toxic chemicals, unlike fabrics like nylon, the raw ingredients for Lycra are not derived from non-renewable resources like petroleum oil. Instead, these ingredients are fully ...
Microscopic algae waft along freely in the water. They form the autotrophic part of the plankton, the diverse group of drifting organisms that inhabits the pelagic zone of everything from oceans to small bodies of water. The name plankton is derived from the Greek word πλαγκτος (...
1. True or false: Laundry stripping should be performed after every wash. False. Laundry stripping shouldn't be done very often — only a few times per year, as over-stripping can cause fabrics to break down. Learn More: What Is Laundry Stripping and Is It Worth Trying? 2. Which dog ...
energy sources like hydropower and geothermal energy are renewable because they don't consume the resources they use, so nothing needs replenishing. Biofuels, derived from organic biomass, still contribute emissions and air pollution, but they are still considered a renewable energy source because they...
An even more interesting aspect is the technological challenge of exploiting the almost unlimited energy resources of the oceans by making use of tidal streams, waves, and currents as well as of differences in temperature or salinity.Footnote30Although the technological developments are still at an ...
Gathering data and applying the power of advanced analytics can help tackle problems in surprising ways. The distressed state of the oceans is a case in point. Decades of overfishing is depleting the oceans at an alarming rate, at a time when the emerging world increasingly depends on seafood ...
