Renewable and non-renewable energy resources
- solar city uses solar panels to create energy
- solar panels can power houses in power outages
- only uses solar energy and not any other type of energy
- solar energy is unlimited and the sun is renewable
- transforming houses that run on fossil fuels to solar
Solar city’s method is to disconnect from fossil fuels because society is becoming further attached to fossil fuels and we have started relying on it as our primary source. That is a huge issue because fossil fuels will eventually be extinct and we will be faced with many concerns if we continue to rely purely on fossil fuels as opposed to solar, wind or hydro energy. We are going to struggle to function without as a society without them.. That is why we need to start integrating ourselves into healthier options for our world
Plans to reduce energy
Purchase energy-efficient products and operate them efficiently. Use an advanced power strip to reduce electricity that is wasted when electronics are not in use. Incorporate more daylighting into your home using energy-efficient windows and skylights. This way, during daytime, your house will be full of sunlight instead of energy usage. For electrical space heating and cooling, consider various solar design concepts to bring into your home, which include using energy-efficient windows and properly insulating and air sealing your home. Select an energy-efficient heating system that doesn't use much electricity.
what is static electricity
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electric charge can be created whenever two surfaces contact and separate There are many uses for static electricity, such as dust removal, photo copying and car painting. An example of static electricity is a balloon and hair, when you rub a balloon on your head it causes opposite static charges to build up on your head and as well as the balloon, when you pull the balloon slowly away from your head, you can vividly see the two opposite static charges attracting one another and causing your hair to stand up.
The transfer of static electricity
Charging by Friction
When two uncharged objects rub together, some electrons from one object move onto the other object. The object that gains electrons becomes negatively charged, and the object that loses electrons becomes positively charged. Charging by friction is the transfer of electrons from uncharged object to another by actions such as rubbing. For example, when a person subs their socks against the carpet, electrons from the carpet travel onto their sock.
Charging by Conduction
When a charged object comes in contact with another object, electrons can be transferred between the objects. Electrons transfer from object with the most negative charge to the object with most positive charge. For example, a positively charged object will gain electrons when it comes in contact with an uncharged object. The definition of Charging by Conduction is the transfer of electrons lead from a charged object to another object by direct contact.
Charging by Induction
During charging by friction and by conduction, electrons are transmitted when objects come in contact with each other. In charging by induction, however, objects do not come in contact when the charges transfer. Charging by induction is the movement of electrons from one region of an object that is caused by the electric field of a second object. The electric field surrounding the charged object attracts or repels electrons in the second object.
Electrostatics, as the name implies, is the study of stationary electric charges. A rod of plastic rubbed with fur or a rod of glass rubbed with silk will attract small pieces of paper and is said to be electrically charged. The charge on plastic rubbed with fur is defined as negative, and the charge on glass rubbed with silk is defined as positive.
Electrical currents are a flow of electric charge. In electric circuits, this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). The SI unit for measuring an electric current is the ampere, which means it is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is often measured using a device called an ammeter. An ammeter is device for measuring electric current in amperes. There are two types of electric circuits, series and parallel, it involves a collection of wires and electric components connected together in such a way that electric current can flow through them.
Efficient energy is the goal to reduce the amount of energy required to provide products and services. For example, when insulating a home, it allows a building to handle less heating and cooling energy to achieve and maintain a comfortable temperature. It also helps to install fluorescent lights, LED lights or natural skylights to reduce the amount of energy required for regular incandescent light bulbs. Improvements in energy efficiency are generally achieved by adapting to a more efficient lifestyle.
There are many ways to improve energy efficiency. One would be to reduce energy use and reduce energy costs and it will most likely result in a financial cost saving to consumers. Reducing energy use is also been approved as a solution to the issue regarding greenhouse gas emissions. According to the International Energy Agency, improved energy efficiency in buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third, and help control global emissions of greenhouse gases.
Energy efficiency and renewable energy are heard to be the twin pillars of sustainable energy policy, they are extremely high priorities in the sustainable energy position. In many countries, energy efficiency is also been noticed to have a national security benefit because it can be used to reduce the primary level of energy imports from foreign countries and may slow down the rate at which domestic energy resources are drained.
DC VS. AC
Alternating current is exemplified as the flow of charge that changes direction periodically. The voltage level also reverses along with the current. AC is used to deliver power to houses, office buildings, etc.
AC can be composed using a device called an alternator. This device is a special type of electrical generator designed to produce alternating current. A loop of wire is spun inside of a magnetic field, which produces a current along the wire. The amount of rotation of the wire can come from any number of means: a steam turbine, a wind turbine, flowing water, and so on. The wire spins and enters a different magnetic conflict periodically, the voltage and current alternates on the wire.
Direct current is a slightly easier to comprehend than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current.
DC can be generated in a number of ways:
- An AC generator equipped with a device called a “commutator” can produce direct current
- Use of a device called a “rectifier” that converts AC to DC
- Batteries provide DC, which is generated from a chemical reaction inside of the battery
