WHAT ARE THE USES OF OCEANS?
WINDMILL FARMS ANSWERS:
Uses of the Oceans covers the Ocean's living and non-living resources with an emphasis on sustainable development, organized within topics:
Disposal of Waste from Land: including sewage, non-point sources, carbon dioxide sink
Energy: including conversion of tidal, wave, thermal (OTEC), salinity and wind energy
Fisheries and Aquaculture: including resources, technology, production, processing, utilization, trade, governance
Human Settlements on the Coast: including coastal urbanization and development, destruction of habitats and other physical alterations
Marine Biotechnology: information on pharmaceuticals, other chemicals, genetic resources and products developed from marine living resources using biotechnology
Non-Consumptive Uses: including clean water, endangered species, marine reserves, habitats, viewing of nature (ecotourism), aesthetic values and amenities
Ocean Dumping and Ship Wastes: including dredging of ports, voluntary dumping, disused oil platforms, discharges from cargo and passenger ships, nuclear waste disposal
Offshore Oil, Gas and Mining: exploration and extraction of oil and gas; gravel, sand and mineral mining from the coast to deep water
Recreation and Tourism: including fishing, boating, swimming, surfing and other types of recreation and tourism, infrastructure development, management approaches, managing the impact
Transportation and Telecommunication: including maritime transport and telecommunications (pipes, cables), navigation, port infrastructure, shipping rules, safety at sea, routes, congestion, accidents, governance
Sharon asks...
WHAT TYPE OF ENERGY ARE THESE?(10 POINTS!)?
Solar Panels
WIND turbines
geothermal ENERGY.
Its confusing me
WINDMILL FARMS ANSWERS:
1- Solar panels use light energy(photons) generated from the sun.
2- It's a device that converts kinetic energy from the wind into mechanical energy.
3- Thermal energy from earth
Hope it helps

WIND ENERGY QUESTION ! EASY 10 POINTS?
what would be a landowner's point OF view on "if the WIND generated power is a good idea or not?"
WINDMILL FARMS ANSWERS:
Wind turbines take up little room, but have to be spaced out. You can use all the land round them for farming, so most landowners with suitable sites are onto a good thing. Its the neighbors that are not earning and constantly reminded of that by looking at the turbines that hate them. Thats why community wind farms are such a good idea, you loose the 'not in my back yard' effect overnight if the locals can invest in them too. It works all over Denmark.

ENERGY CONSERVATION IN ANNIHILATION?
If we manage to create a large amount OF antimatter and manage to hold it, are the scientists really going to be happy? I mean.. OF course matter-antimatter annihilation will cause huge bursts OFENERGY but creating the antimatter required the same amount OFENERGY no? OF course it will be better IN terms OFENERGY supply like a spaceship or something i mean, all the ENERGY required to create the antimatter, all the electricity and all, is concentrated IN a small package but will it be that amazing? OF course, finding a planet made OF antimatter would be insanely amazing, but i feel like pple are saying that as soon as we "create" large sums OF antimatter well get more ENERGY than before, which makes no sense..
WINDMILL FARMS ANSWERS:
Antimatter used for its energy is many, many years off, but you are on to something. Namely, recognition of the difference between an energy source and an energy storage device or scheme.
When you hear talk about sources of energy, this crucial distinction is almost never acknowledged. Fossil fuels, hydroelectric, wind, solar, nuclear, including fusion energy if it can ever be made practical -- these are energy sources, because the useful energy we can extract from them is far greater than the energy expended to 'make' or 'refine' them, or do whatever is required to get the energy they can yield.
Hydrogen cells, battery power for vehicles, and yes, antimatter, if we could produce, store, and transport it safely in quantity, are energy storage media, not true energy sources, because more energy must be expended in producing them than they will supply -- more, not an equal amount, because no energy transfer/transformation process is ever 100% efficient. (Of course, if we discover a supply of existing antimatter, this could be in the first category -- an energy source -- that is, if some very steep difficulties in collecting and handling it can be solved.)
But just because something is an energy storage medium, and not a true energy source, doesn't make it useless, because there can be advantages in removing the actual production of the energy from its point-of-use. For instance, if you have a few factories turning out enough hydrogen cells to supply significant amounts of energy all across the country, or around the world, then you've concentrated problems like pollution in a few isolated spots where they can more easily be dealt with.
Now having said this, it should be noted that this distinction stems from the practical matter of how the energy is used, not from the laws of physics, per se, since all energy (actually, mass-energy) is conserved, so if we use it, it had to be produced somewhere at some time. So it's really a matter of distinguishing between energy that's already 'there for the taking' vs. Energy we have to use some other energy source to 'make.'
But yes, this is a very important distinction, because if you wanted to 'swap out' some true existing energy source for something that's merely an energy-storage medium, you won't be able to -- think of it like the battery in your cell phone, vs. The electric outlet on your wall. To you, the latter is an energy source, because you can keep using it; the former, a mere energy-storage medium, which you can't keep using without that outlet to restore its charge.
