The true cost of renewable energy

With a lot of efforts being made to shift to renewables as major sources of power, there has been a lot of concern whether it can effectively compete and finally replace other methods of energy generation. Indeed, there has been an increase in the amount of renewable energy generated and added into the energy mix, with global figures showing that 143 gigawatts of renewable energy were added in 2013. It is expected that the rate will shoot to four times the current rates by 2030.

To begin with, popularity of renewable energy generation sources is due to their low environmental impacts - this is the most important reason they have been aggressively pursued even to date. Renewable energy is the perfect way to avoiding a climate change fueled by a 2 degrees Celsius benchmark rise in global temperature.

There has been no other time when governments and non-governmental organizations have raised up against acts that damage the environment like in the last few years. However, there is no doubt that the world started at a challenging point with regard to pricing of renewable energy although proponents still think that renewable energy is cost-effective on a long term basis.

A hands-on comparison of LG G4 vs LG G3; the LG's latest Smartphones

LG released G4 Android Smartphone this April

LG G4 and LG G3 are amongst the world's best smartphones today (in 2015). After releasing the LG G4 in April 2015, LG has reconfirmed it is working on a new device that will compete with the Samsung’s Galaxy Note. The company has said that the device will stand above the G category and will be released by second half of this year. The news also comes after the release of the LG G3 last year. LG has upgraded a number of features on the newly released LG G4 while maintaining the exclusive features of G3.

The latest device uses the Android 5.1 Lollipop with an UX 4.0 UI interface that makes it easy to navigate, especially with animations. The Android software also makes the phone to accommodate Overview, which is the latest approach to apps. Users will also enjoy the digital assistant service, Google staples, and lock screen notification, among other features. G3 uses Android 5.0.

A complete review of the Google Nexus 6

Google Nexus 6

The Motorola-made Nexus 6 marked the debut of Google’s Project Fi, which is a cellular network. However, Nexus 6 is also being sold by many carriers across the world, including AT&T, T-Mobile and Sprint. But Nexus 6 is not for those who won’t live with a presence-sensing Moto Active Display or the one-hand texters. The phone is considerate although Samsung Galaxy S6 Edge performs better with its flashy design and HTC One M9 for its premium feeling.

Design

Nexus 6 is a two-handed supersized version of phablet-sized Smartphone. Due to its huge size, users will afford a better grasp. It is a Moto X development, so something must have been borrowed from Motorola: an aluminum metal frame and a gently curved back. The contoured side is at 3.8mm in thinness while the thicker hump of the slope is 10.1mm. If you love the edge-to-edge display that implements no buttons, this Nexus project is fit for you.
The back is made of plastic but manages a smooth feel on hand and deviates from the all-metal casing Android offerings. The plastic back on the Midnight Blue leaves smudges. However, it doesn’t incorporate the far-too-supple leather backs used on Motorola phones or the wood finishes. The phone is heavy at 184g so Samsung’s Galaxy Note 4 is better in comparison at 176 g. It is available in Cloud White or Midnight Blue colors. The phone also supports Qi wireless chargers. Its knock-to-wake feature does not work consistently too though it does sometimes light up the greyed-out screen. It comes with front-facing speakers that have a stereo sound. The latter is comparable to HTC One M9’s BoomSound technology.

Five things you should do daily to live a healthy and happy life

How happy is a person born with beautiful physique and healthy bones! But, healthy lifestyle is the basis of a happy life regardless of whether you are born healthy or weak. Therefore, constant human efforts are needed to keep this happiness persistent and healthy looks maintained. Healthy figure not only helps you feel good about yourself but also lowers the rate of depression which is a big issue in today's fast and competitive world.
Balanced lifestyle beautifies you in skin, covers-up your dark circles, provides you with lots of energy to carry out daily tasks and improves your psychology, thus adding success to your life-meter. No doubt, a dark patchy skin, bad health profile and feeling of low energy are the main reasons at times that make you step back in your motivated life. Given below are five daily routine things you should do to live a healthy and happy life.

New design could lower the cost of solar panels

The solar power market is expected to exceed US$180 billion by 2021 according to this year’s report by ResearchMoz, with China playing a key role in the growth due to its massive investment in the sector. There is no doubt that this endlessly available source of renewable energy is highly useful, with the world now looking for better options to harmful coal power generation. Reducing the cost of solar power is detrimental to this endeavor, and new technology plays a huge role towards this. The cost of production of solar power on a large scale remains high with the benefits for integration into the grid falling short of its benefits. In fact, although new technologies such as Photovoltaic systems have played an important role in reducing costs, further innovations are needed to reduce it further.     

Researchers have found a new way of arranging ingredients in a polymer solar cell, which could help to lower the cost of solar panels. A team of scientists from University of California has discovered that the new design can be achieved by rearranging polymer strands (acting as charge donors in the solar cell) and carbon molecules (acting as charge receptors) in a manner resembling plant cell components that trap sunlight energy and separate positive and negative charges. Polymer solar cells are one type of photovoltaic technologies but differ from the traditional solar cells in the way power is generated. They carry advantages such as ;
  • lower weight, 
  • easy to fabricate via the roll-to-roll technologies, 
  • recyclability, 
  • and utilization of environmentally friendly materials. 
Their penetration has been lower compared to the silicon-based types due to their power conversion efficiency.

Tesla's Powerwall battery to power your energy needs cheaper and more efficiently

Tesla Motors | Powerwall Battery

The world is expecting the revenue in energy storage industry to reach $19bn by 2017 according to research released by IHS CERA. Earlier this year in April, Tesla announced the release of a battery that is set to cut down the cost of power in homes by providing 7kWh of daily cycle power. The 1.3m by 68cm Powerwall can be hung inside a garage or on the outside of a wall at home. The company also said it would provide businesses with a 10kWh backup model that can replace backup generators.

So it was reasonable that Tesla CEO Elon Musk could address a number of criticisms. He said the company will, in response, double the power output on the home battery system to allow usage on every device at home except air conditioners. The daily cycler, which costs about $3,000—$3,500, according to him, will be of limited use in the United States and it is best for complete off-grid applications. It turns out that it would be fit for people who care about use of renewable energy more than the economics of it in the United States. In fact, in places like Canada, the cost of power is as low as $0.06 per kWh and most cities in the United States can afford a cost of about $0.15 per kWh for grid power. In comparison, solar power energy cost comes at about $0.2 per kWh and more expensive when you consider the cost of peripherals. This does not mean it does not make economic sense in other regions.
