Many societies still get most of their energy from fossil fuels such as oil, coal, and gas. Studies have shown that burning such fuels may be a cause of climate change. There are several sources of energy that humans could use instead, each with pros and cons.

Solar power uses energy from the sun to produce electricity. When sunlight hits a device called a solar cell, it causes electrons to move. This creates an electric current. Solar power causes no pollution and is completely renewable. Unfortunately, solar cells are costly, although the price is coming down. Moreover, solar energy cannot be produced efficiently on cloudy days.

Wind power is another source of clean, renewable energy. Most wind power comes from large structures called turbines that have three long blades. The wind spins the blades and produces electricity. A single large wind turbine can generate enough power for about 600 modern homes, but wind turbines can be expensive and are affected by the weather. In addition, the turbines are considered large, unattractive, and noisy by many.

Hydroelectricity turns the energy contained in water that is falling or flowing into electricity. Hydroelectric power plants are usually located near dams. Water can either be pushed through pipes to turn generators, or turned into steam. Dams are generally cheap and clean to run, so hydroelectric power is not expensive. However, to build a dam, it may be necessary to move people from their homes or destroy the places where animals live.

Many species—whether plants or animals—have used the oceans to move around the planet. By swimming or riding on floating objects like logs or leaves, these organisms have found new places to live. Their movement depended largely on ocean currents and winds. However, this changed when humans began to travel long distances by ship. Today, as a result, organisms can travel faster and farther around the world.
An invasive, or non-native, aquatic species is any organism that exists in or near water where it does not belong. When a foreign species arrives in a new location, several things can happen: It can find its new habitat unwelcoming and die off; it can survive with little environmental impact; or it can take over, harming the native species in a number of ways. Invasive species that thrive usually do so because their new home lacks natural predators to control their population. They do damage mainly by eating native species, by competing with them for food or space, or by introducing previously-unknown diseases.
One infamous example is the zebra mussel, accidentally introduced by a cargo ship from the Black Sea into the North American Great Lakes in 1988. The little shellfish multiplied quickly. Many of the Great Lakes’ original mussel populations died off because they could not compete with the zebra mussel for food sources. The zebra mussels also affected human structures by attaching themselves to anything from factory intake pipes to ship rudders. They have now spread from Canada to Mexico and are considered a major problem. Hundreds of millions of dollars are spent every year to try to control them.
To combat invasive species, governments are mostly focusing on how to handle ship ballast. This is seawater that ships carry in a tank to provide balance on journeys. On arrival, the water—along with whatever species happen to be in it—is released. New regulations in some countries require ships either to exchange their ballast before they enter a freshwater port, or to treat it with chemicals to kill invasive species before release.
