Tesla Powerwall: you and me can live off the utility grid


Last week, Tesla announced the so-called Powerwall. The Powerwall is a home battery that can be charged via solar panels or via the grid when utility is low. By using the Powerwall, electricity can be stored when the sun is out and it can be used when electricity demand is the highest. Furthermore, the battery can be used as an emergency backup in a power failure as well. [1] Tesla also announced the Powerpack, which “is designed to scale infinitely”[2] and is targeted to (large) businesses. However this article will focus on the Powerwall to see whether it’s you and me can that can add value to a more sustainable world.

So, how is the electricity demand distributed? First, in the morning there is a peak in the amount of electricity used. You are not having breakfast in the dark, right? Then, during the day the electricity demand is decreasing rapidly. For instance, less light is being used and devices are using their batteries (thing about mobile phones). Last, the electricity demand is going sky high in the evening. Think about your own evenings: you are using your oven to prepare your meal, then you’re switching on your TV to watch a movie and then you put on multiple lamps to brighten your living room. Tesla’s Powerwall can store electricity produced during the day, to meet the electricity demand peak in the evening hours.

By using Tesla’s brand new product in combination with solar panels, consumers can become fully independent from the utility grid. Consumers can start adding value to the world’s energy efficiency usage themselves! There is no need to point fingers at the big energy providers; you can take action yourself. But does the Powerwall provide the perfect solution for all of us? No, not yet. In an article about the Powerwall, Christopher Helman (Forbes) describes that Tesla’s latest innovation doesn’t make economic sense unless your house is solar panelled and entirely of the grid.[3]

Although the Powerwall isn’t economically feasible yet, the US government announced 30% federal tax credits of the battery price. Furthermore, California has a 60% be-a-fool-to-not-try-this rebate.[4] These rebates will increase the adoption of the Powerwall among people who can afford it and who are willing to live more sustainable. The income generated via the early adaptors can be used for further development of the batteries, which then will lead to decreasing prices. Besides, prices for solar panels are decreasing as quickly as batteries nowadays. Therefore, there is a huge potential market for Tesla: more and more consumers can start adding value to the worlds energy efficiency.

To conclude, the introduction of Tesla’s Powerwall allows consumers to start living completely off the grid. Although it’s not economically feasible for the entire world yet, it’s a great first step. Early adaptors and innovation will lead to decreasing prices and more Powerwall users. So from today, let’s start adding value to a more sustainable world together!

Are you ready to beat the ‘Snake’ high score again?!


In the past, Nokia has been the dominating player within the mobile phone industry. If you never have seen the 3310 model or played ‘Snake’ on one of the previous Finnish devices, you were probably born after the launch of the 3310 model in September 2000 (Techradar, 2014). In the upcoming years, Nokia’s senior management didn’t believe that the smartphones would conquer the mobile industry. A clear lack of vision: 1.2 billion smartphones were sold last year (NRC Q, 2014). When Nokia finally started selling smartphones, other players were already dominating the market. Nokia’s sales were dropping and the mobile department was sold to Microsoft in 2014.

Last week, Re/code announced that Nokia is planning to return to the phone market in 2016 (Re/code, 2014). Initially, Nokia agreed with Microsoft not to manufacture any mobile phones until 2016. Although this agreement was signed, the Fins are allowed to sell Nokia products if manufactured by another company. Using this loophole, Nokia can start selling phones again (Emerce, 2014).

It will be difficult for Nokia to attract customers when entering the highly competitive smartphone marker. Often marketing spending is invested in sales promotions to influence customers’ buying behaviour and attract new customers (Kim et al., 2014). To determine what the best strategy is for attracting new customers, Kim et al. (2014) compared price discounts and sampling to a more innovative method called pay-what-you-want (PWYW). When using a PWYW strategy, customers are able to determine the selling price themselves.

Kim et al. (2014) found that PWYW is an entertaining way of promoting products to consumers. It can both lead to a higher word-of-mouth effect and more consumers that want to benefit from the promotion. Furthermore, the researchers found that the prices paid in a PWYW situation are significantly different than zero. So, PWYW is not just a fancy name for free sampling; people are more likely to pay for products even when they can get it for free (although the price paid is lower than the original price). PWYW can be an attractive way for Nokia to get in contact with potential customers and to create a positive hype (Kim et al., 2014).

Compared to price discounts, in a PWYW situation consumers tend to pay less for a certain product. But, since PWYW attracts more consumers, Kim et al. (2014) found that this effect was compensated. If Nokia wants to settle in a highly diversified market again, it’s very important to reach a high number of customers. Instead of competing the current smartphone providers using price discounts, Nokia should use a PWYW strategy to reach more people and while earning more money.

Smartphones are expansive products. Therefore, using a PWYW strategy to conquer the market can be risky. Although Kim et al. (2014) didn’t investigate the effect of it, they suggest using PWYW in a more restricted way in these cases. For instance, consumers can determine their discount based on a predefined list of discount percentages. By doing this, Nokia can influence the magnitude of the promotion but still take advantage of the PWYW benefits.

Using a PWYW strategy can provide Nokia with a lot of new, and recurring(!), customers. So, are you ready to beat the Snake high score again?

You and Me will Shake Up the News Industry


Using your Twitter account to create your own TV channel, something that became reality last February with the introduction of the Meerkat app. It’s very easy: open the Meerkat app, log in with your Twitter account and press ‘stream’ to start broadcasting. The broadcast will be shared via your Twitter account and can be followed by any other Twitter users.[1]

Meerkat is a promising application: the start-up got over 4.2 million dollar in funding and has over 120,000 users already.[2] Furthermore, after the successful introduction of Meerkat, Twitter launched its own streaming application called Periscope. Both Meerkat and Periscope allow Twitter users to broadcast anything they like. I’m conviced that these streaming apps will shake up the news industry.

Already, news organisations started experimenting with both Meerkat and Periscope. The Economist correspondent Henry Curr answered questions send in via Twitter, using a Meerkat stream. According to the Economist, ‘Meerkatting’ is perceived more informal and a great way to engage with their Twitter audience.[3]

Twitter already got a great impact on the news industry. 78% of all journalists use social media on a daily basis (of which Twitter is used the most) and 74% of all journalists believe that social media have more rapid impact than traditional media. But it’s not the news organisations that will shake up the industry; it’s going to be you and me.

Already, consumers are adding value to the news industry by sharing information about any kind of occurrences on social media (both text and pictures). This is already being used by journalists to pick-up the latest news flashes: 45% of all journalists put out 60%-100% of all they publish as soon as possible – without checking facts – and correct later if possible. Just 20% of the journalists always check the facts before publishing.[4] Via the streaming apps, consumers can start adding value to the news industry by sharing directly what they see: it’s an additional point of view next to traditional news organisations and, moreover, viewers can interact with the broadcasters. Concluding, you and me can help sharing news quicker and more reliable.

So from now on, news organisation are becoming of less importance in providing news to societies? No, that’s a misunderstanding. Meerkat and Periscope were widely used after an explosion in York City. Some were stating that these broadcasts were introducing a new era of journalism, while others were less convinced by the usage of the streaming apps. Jacob Brogan, Future Tense research associate, stated that “People weren’t getting information from either that they couldn’t have found more easily and more clearly on Twitter” because “it was too far from the scene to reveal more than the fact that the fire was still burning”.[5] I do not think that Brogan isn’t right there, but the ‘Meerkatters’ aren’t replacing journalists. While news organisations will remain the most reliable source for news, ‘Meerkatters’ can show news from a different angle and, moreover, followers can interact with the Meerkatters.

You and me are not going to take over news organisations – we shouldn’t even want to do that – but we are going to add value to the news industry!
