Best ways to conserve energy at home – reduce electricity consumption and save heat energy
Why do we need to conserve energy at home?
In the USA, the amount of energy used in private homes is around 21% of the total country’s cons...
Renewable resource – soil?
Is soil a renewable material?
Some natural resources, such as sunshine, win and geothermal power are renewable resources but others are not so obvious. A definition of renewable might be ‘a resource that...
Which resource is renewable?
One resource that is both renewable and inexpensive is sunlight, i.e. solar energy. The benefits of geothermal energy are also being exploited more and more, as it’s one of the few truly renewable ener...
5 disadvantages of non renewable resources
Disadvantages of non renewable resources:
Exploration and conversion takes time and resources.
Diminishing resources – non renewables are disappearing.
Causes pollution and emits greenho...
The biggest problem with solar energy has persisted since the dawn of time – the absence of sunlight during the night. That means that the solar energy supply can be easily disrupted during the night and on overcast days. Solar pa...
You can run a house with 28-32 solar panels on average. For a 2,500-square-foot house, this will pay 100 percent of the energy bills. The actual number of panels you’ll require depends on the size of your home, panel positioning,...
The biggest problem with wind turbines is that they can be loud and unsightly, sometimes harming the physical environment. Another problem is that wind power, like solar power, is inconsistent, meaning that turbines are weather de...
The top 5 advantages of solar energy are:
Solar energy reduces home electricity bills
Use of solar helps the environment
Solar power is versatile, just like electricity
Solar energy is reliable as it depends on sunlight
Implement...
Many people wonder if it’s OK to leave solar panels disconnected when they are exposed to the sun . Yes, it’s OK. Nothing happens to them. Solar panels will generate electrons when sunlight strikes their surface, but with no close...
How long will a 100W solar panel take to charge a battery?
Charging 12 volt batteries with solar panels is a great way to use natural energy from the sun. However, there’s a few things we need to know before matching the correct s...
A Solar Charge Controller regulates the voltage and current flow from solar panels to a battery. It detects and monitors the battery voltage, reducing the current when the battery is fully charge. The controller maintains a float charge to keep the battery ready for use.
A 100 watt solar panel cannot run an average size refrigerator. It cannot generate enough power as the average size of a domestic refrigerator is 400 watts. A refrigerator with combined freezer has an average power rating of 700 watts.
