When we talk about getting energy “off the grid”, we’re talking about an alternative power source to bring electricity into your home. Power companies create electricity through huge generators. That electricity is then shipped through wires across long distances and into individual homes by power poles and wires. Most people who want power contact their local utility company. That company then sends someone out to connect the wires from the electric poles to their home.
11. Assume you might be wrong! Monitor your decisions and actions to make sure the results are on track and no unintended consequences are showing up.
It is often presumed that self-sufficiency in energy is only for nerds, but this is not true, it is now within the reach of every family or household. If you have lots of money, a solar or wind powered system will cost you about $45,000 and it will take about ten years to recover your investment by getting off the grid. However, you can have the same apparatus for much less than half that amount.
On your appliance you will see the number of watts that each appliance uses. A washing machine creating its power supplier own hot water for example might watts. This is 2 kilowatts per hour.
Compared to other energy platforms, hydropower is very efficient. Energy conversion rates are in the 80 to 90 percent range. The plants also have a long life as you can see with any dam, and maintenance costs are relatively low. Cost of energy production, thus, is lower or on par with other energy platforms including oil.
Tidal Power is unique because gravitational force, not radiant energy from the sun is its source. The only other energy sources currently available that don’t ultimate originate from the sun are battery power and nuclear power.
When compared to the United States, the efforts of China are amazing. We often view China as a country “catching up” to the rest of the world. With the large investment in renewable energy, it is clear that China is now leading in the energy arena instead of following. Perhaps those future conflicts will not come to be.
