What are the solutions for increased energy prices? Our planet has limited fossil fuel deposits, but endless green energy possibilities, mostly due to the Sun that illuminates and warms us every day, the Moon that produces the tides, the weather conditions that produce the winds and the Earth that favors geothermal energy.
After a heavy pollution of the planet, nature send us several signs in a form of heat waves, heavy rains and floods, drought conditions in many countries and massive forest fires which produced great harm to human life and properties. These signs have been just warnings about what we can expect if we continue to pollute and disrespect our home planet.
Many studies and researches conducted on climate changes exposed some disturbing realities about humanity as the primary factor that causes these climate modifications. All greenhouse gases generated by humans can be the consequence of the human activity and it seems that these activities are harming the environment and can produce devastating effects on the climate balance of the entire world.
To avoid any catastrophic climate changes we must slowly, but surely lower our carbon based economy that is still burning fossil fuels every day. To lower the carbon footprint of the world industry we need to find and use a few replacement resources that are the renewable energies. As the society evolves and energy demand increases, for the near future we can combine fossil fuel burning with renewable energy generation, in order to cover all our energy necessities especially for growing economies.
In time, we need to improve all these green technologies in order to increase their efficiency to become competitive in the battle with the fossil fuels energy market. Because the price of the fossil fuel produced energy is increasing every year, besides the ecological obligation we also have a financial one to install and use alternative energy devices which have the ability to lower our energy bills.
The US, as a world leader in pollution, must make the first steps in order to create almost free possibilities for a homeowner to install and use a renewable energy device. In Europe, countries like the UK or Germany can be the promoters of the renewable energy use in every home, in order to lower the carbon footprint.
By simply changing all these appliances we have already lowered our house carbon footprint. If we install a few solar panels or a wind turbine system at home, we will further decrease our carbon footprint along with a reduced cost with the energy bills.
Homeowners that produce plenty of green energy and have an excess of it, can earn more money by simply returning this excess energy back to the grid and helping the energy company to power other homes.
As a conclusion, we know what we have to do in the near future in order to save and conserve our planet from possible climate disasters.
In the future they can also help low income households to change their old appliances with new, more green ones.Formerly, which referred to persons, but this use, while still heard (a man which I know), is nonstandard. Contrary to the teachings of some usage guides, which introduces both restrictive and nonrestrictive clauses.
The “rule” that which can be used only with nonrestrictive clauses has no basis in fact. Energy harvesting (also known as power harvesting or energy scavenging or ambient power) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), captured, and stored for small, wireless autonomous devices, .
