Have you ever wondered if what you know about the causes of land pollution is accurate? Consider the following paragraphs and compare what you know to the latest info on the facts about solar energy.
Solar energy is energy from the sun. When the sun is shining solar energy is being produced as it sends the heat radiating to the earth. Solar energy is as plentiful as daylight, as limitless as organic life itself, a fuel that comes free of charge and replenishes itself every time the earth rotates on its axis. Almost all energy, after all, is ultimately stored solar power: Oil, gas, and coal were born of the ancient sunlight that fed prehistoric animals and plants, the wind is set howling by the sun’s unequal heating of the atmosphere, and even a campfire draws its warmth from solar power trapped long ago through photosynthesis.
Solar energy is produced at the core of the sun by nuclear fusion. This energy is then radiated to the convection zone, where mixing transfers the energy to the photosphere. Solar energy can be used for powering home appliances and a solar water heater can give you hot water for laundry and normal household use (bathing, preparing meals, cleaning). Look for the most efficient and cost effective options for your solar home. Solar energy will fall in price to match the cost of conventional fossil fuel electricity far sooner than previously expected, the UK’s largest solar company has claimed in a new report. The solar company said British homeowners will see solar achieve “grid parity”.
Think about what you’ve read so far. Does it reinforce what you already know about the causes of land pollution? Or was there something completely new? What about the remaining paragraphs?
Although HFCVs are much less efficient than BEVs, wind-HFCVs are still very clean and were ranked second among all combinations. Wind turbine designs have undergone dramatic changes since the first windmill structure invented in’88 by Charles F. Wind energy and tidal energy also feature among the many and varied articles. These discuss the principles behind these alternative energy sources, the need to move away from fossil fuels and greenhouse gas emissions.
Solar energy research is expanding rapidly, with many new ideas being explored – some using exotic nano-materials combined with ingenious engineering approaches. PVs look set to contribute significantly to future power generation. Solar energy use accounted for 129 kilo tons of oil equivalent (ktoe) in 2000 and is projected to be 431 ktoe and 828 ktoe in 2010 and 2020, respectively.
Renewable energy provides more jobs per unit of output and per dollar spent than conventional energies do. Economic woes and high unemployment rates influenced Spain’s 94 decision to invest in renewable energy. Renewable energy is no less reliable than energy generated from more traditional sources and using it does not mean that you have to change your lifestyle or your appliances. Using renewable energy can be as simple as using the sun for drying clothes or can mean taking advantage of more sophisticated renewable technologies, such as photovoltaic (PV) cell systems, which use the sun’s heat and light to generate energy, wind turbines or ground source heat pumps which extract energy from underground. Renewable energy is important for the environment as it produces little or no greenhouse gases. The exception is biomass which is considered as being ‘carbon neutral’.
So now you know a little bit about the causes of land pollution. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.
