Smart Ways You Can Conserve Energy During The Summer

Ways You Can Conserve Energy During The Summer

Summer is the perfect season for energy savings. With the warm weather and longer hours, you can take advantage and use much less energy than you will in the other seasons. This article outlines 5 ways that you can conserve energy during the summer months.

Run the air-con less:
Just because it’s summer doesn’t mean you need to run the air-conditioner 24/7 in order to be comfortable. Save the air-con for the really hot days when a fan just won’t do. On warm days a fan will often suffice, especially if just one or two people are home. There is no need to cool an entire home when only one room is being occupied. Also make sure that you are not always blasting the air-conditioner. You might be used to it creating a slight chill in the house, but you don’t need it to be that cold inside. Lowering the setting on the air-conditioner will save you energy.

Open the curtains:
During the longer months you will not have to turn on lights very often. If you tend to keep your curtains closed, it might seem darker than it is causing you to turn on lights when they’re really not needed. Open the curtains and let the light in. If you still have thick, dark coloured curtains up from the cold winter months, take them down and replace them with lighter ones that will allow in more natural light. This will also allow the breeze to flow through more easily when the windows are open, helping to cool your home.

Take advantage of public pools:
If you have a pool, you know it takes a lot of time and energy to fill it and keep it running. Just because you have a pool doesn’t mean that you have to use it all the time. If you only plan on swimming for a day, it’s better to go to a public pool.

Bake less often:
Baking in the summer is counterproductive. You don’t want to do anything that will make your home warmer than it already is. If you bake during the warm months, you will heat your home and then run your air-conditioner to cool the house down again. The less you use the oven and stove during the warmer months the more energy you will save. In the summer most people prefer light and cool meals. Those kind of meals will require less of the oven and stove, which in turn will save you energy.

Dry laundry outdoors:
You’re probably not going to wash your laundry by hand, but you can certainly hang your washed laundry outside to dry. Take advantage of the warm, sunny days to do laundry, so that you can avoid using the dryer.

 Summer is the perfect season for saving energy. You don’t need to heat your home, use the lights as much, or even use the oven as much as you do during the rest of the year.



Groundbreaking Solar Power Strategies

Developing solar power resources is an important component of any contemporary energy plan. Because solar energy is free, clean, renewable and domestically available, it offers many benefits to consumers, governments and the environment. Meeting energy needs with solar power reduces exposure to unstable foreign oil markets, curbs dependence on climate-harming fossil fuels and lowers utility bills. Solar innovation helps create competitive renewable energy markets. Discover three groundbreaking strategies that are helping to make solar power an everyday reality.

Lower the costs of non-hardware components.
Over 60% of the costs of implementing a solar power system comes from non-hardware components. Strategies focused on the acquisition, financing, contracting, permitting, connection, inspection, installation, performance, operation and maintenance of solar photovoltaics (PVs) aim to reduce the cost of alternative energy systems. Making cost-benefit information transparent, as well as educating solar professionals, is an important step in promoting consumer confidence. As consumer confidence rises, more people are apt to embrace solar-electric systems. Financing solutions include working with lenders, businesses and households on financial models, leasing agreements and purchase agreements.

Costs of installing PV systems can rack up at many levels of government. Streamlining small-scale and large-scale compliance and proper permitting at local, state and federal levels is an important solar strategy. Curbing resources and time by developing efficient processes helps saves consumers money. Efficiency can also be improved by training workers on better procedures. Enhancements in solar technology help increase the dependability and function of PV systems. Maintenance and operations strategies include research and development in the planning, designing and monitoring of solar photovoltaic systems.

Create a solar-friendly environment.
Creating a climate in which solar innovation can thrive is important for bringing efficient, effective and affordable sun-driven technology to life. Tactics in this area include removing restrictions in connection and metering, creating renewable portfolio standards and eliminating obstructive ordinances and codes. Attracting investors to solar projects is also a crucial component of creating a competitive renewable energy environment. Increasing access to capital while reducing risks through special entities like real estate investment trusts (REITS), master limited partnerships (MLPs) and crowd funding helps to grow strong energy markets.

Solar Power Offers the Greatest Opportunity to Rid Ourselves of Fossil Dependence.

The demand for alternative energy sources has skyrocketed in a world with ever-rising energy needs and ever-diminishing nonrenewable energy sources. In contrast to the environmental damages caused by the extraction and burning of dwindling fossil fuels, alternative energy sources promise renewable and often inexhaustible energy with little to no lasting environmental damage. Today, solar power offers one of the greatest opportunities to turn away from inefficient fossil fuel dependence.

The sun has powered the world’s ocean currents, winds, rain, and all the earth’s biomass growth for millenniums. Today, with the growth of modern technology and scientific progress, humans are able to utilize and capture more power from the sun than ever before. There are two significant ways this captured solar power can be utilized: electricity and heat energy.

For both electricity and heat energy, capturing solar power is made possible by employing solar cells in either flat plate receivers that collect incidental solar intensity and can operate in diffuse light, or by means of concentrators that collect higher solar intensities but operate poorly in diffuse light. Flat plate receivers are more commonly known and are often used by homeowners and small businesses. These are the receivers that have cells fixed across a horizontal plane and take the shape of a rectangular prism. A flat plate solar system will respond to radiant energy regardless of cloud cover, but operate overall at a lower intensity than concentrator systems. Concentrators are more commonly used in large energy production, as in town electrical production. These systems operate by focusing parallel beams of light onto a line (parabolic trough) or a point (parabolic dish). Concentrators reduce the amount and size of the cells needed as each cell’s efficiency is improved under concentrated light, but because of this desired concentration they fail to produce energy in heavy cloud cover.

Both these methods utilize solar photovoltaic power (solar) technology, in which the sun’s radiation is directly converted to electricity through solar cell arrays. The word photovoltaic refers to this turning photo (light) into voltaic (electrical current). In PV technology solar cells are constructed of semiconducting materials, and when the cell’s atoms are hit by light they absorb photons which disturb the atom’s electrons. These electrons are then ‘knocked loose’; a friction that creates an electrical current. Importantly, the solar cells are converters, not sources nor storehouses of energy. Also, for every electron knocked loose, another flows back into the cell, making solar cells a constantly renewable energy source. The solar cell acts as a part of a circuit; the electrons travel a continual path, receiving energy from the sun and transferring it to the load before returning to act again as a receiver. The electrical current created by the knocked electrons is transferred to an inverter where it is converted from direct current (DC) electricity to alternating current (AC) electricity. Inverters produce power at desired voltages for appropriate use.
