Renewable energy – Is it a common man’s cup of tea?

I came across an article on a young graduate in renewable energy engineering. The fellow was doing technical sales and marketing jobs for renewable energy products though he felt that as a graduate, he ought to be doing more than just sales. His, sentiments, I can relate with but again thinking about the field of renewable energy, how many people understand what it is, its importance/ benefits, how to acquire it, its installation, costs etc.? Renewable energy is energy generated from natural resources. The renewable energy sources include sunlight, wind, rain, tides, geothermal heat and various forms of biomass. These sources are renewable naturally and continuously replenished, therefore this energy cannot be exhausted. Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and bio-fuels for transportation. Back to the aspiring young professional who felt that his place in the renewable energy sector lies in doing strategies and coming up with new products-the advice fronted to him was that doing technical sales is the best job for engineers, as it helps them impact on users of their products. Sales entail interacting with customers and knowing their needs so that the product features can be enhanced to suit the customer?s needs. Now, that is brilliant and accurate advice. It is however important to take into consideration that renewable energy is not a common man?s cup of tea and right now the focus all over the world is to build green economies. To me the need for more and more people to understand the benefits, savings and cost of renewable energy cannot be overemphasised. Effort should be made to keep marketing of renewable energy products/ services simple and conversational by avoiding use of acronyms or jargon explaining about operational details. More impact can be made if a marketing rather than technical sales approach is used. Technical sales have been described as boring (can be used as a sleeping aid), tends to use extensive vocabulary, jargon and acronyms that product users cannot relate with and tends to discuss the products technical aspects as opposed to the benefits to the customer. Fun should be created out of all this by making things simple and demonstrating cost savings and benefits of renewable energy.

Large scale corporate transformation

Large scale corporate transformation are the necessary actions required to increase performance in an organisation. It leads to greater performance results and greater organisational growth. It is a lasting change and can range from getting new leaders to combining the functions of different departments. It can also involve the introduction of a new phase in the life of an organisation. Large scale corporate transformation can be measured using three variables. The first variable involves determining how deep the change penetrates to all levels of the organisation. The second variable measures how entrenched it becomes in the organisation while the third measure determines the percentage of the organisation covered in the change.

Corporate transformation is essential for a company that seeks to have a greater impact and a longer life in its business sector. The process requires time and resources. The whole establishment needs to support it for success. Not only does the top management need to back it, but stockholders and staff members also need to buy the idea. This is because when the process of corporate transformation hits a barrier, it will take the entire organisation to keep it on course and complete the process. Without the support of everyone, most organisations will not complete the process.

Business transformation in recent times has begun to combine finance, HR and IT departments into one functioning piece of an organisation. This has resulted in leaner, faster, and more efficient corporate entities that produce high results and has a greater impact in its overall functioning. These three key departments are the backbone of any organisation, and the combination of the three creates an efficient organisation that translates into high performance results.

One crucial aspect of large scale corporate transformation is IT transformation, which entails the entire overhaul of any organisation’s technology systems. It adopts a more efficient platform that enhances its overall operation. IT transformation involves the use of Service Oriented Architecture (SOA) and open systems. This process is the revamping of the existing technology used to support the organisation and is critical for aligning the business functions to the mission of the organization. It touches on the current hardware and software and how they can best be improved upon for greater results. This process is necessary in the entire business transformation.

The question that needs to be addressed is how any organisation can make this process successful. First, it requires the understanding that it is not just a goal to be achieved, but a new way of thinking embraced by the entire organisation. Secondly, the leadership in place needs to be fully involved and dedicated to the process and to realise that it takes time and effort to complete such a mission. There also needs to be flexibility and adaptability in order to learn from mistakes and keep moving forward. Constant communication is also critical to ensure that everyone involved understands the current stage and the next steps to be done. Change is the only constant and is necessary for progress and success.

Monitoring Water Banks with Telemetrics

Longstanding droughts across South Australia are forcing farmers to rethink the moisture in the soil they once regarded as their inalienable right. Trend monitoring is an essential input to applying pesticides and fertilisers in balanced ratios. Soil moisture sensors are transmitting data to central points for onward processing on a cloud, and this is making a positive difference to agricultural output.

Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.

The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of online data and a safe place somewhere in the cloud to curate it. Sentek is in the lead in places as remote as Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.

This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily re-positioned to other locations as crops rotate.

Peter Buss is convinced that measurement is a means to the end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By monitoring that need accurately, that water can be saved until later when the plant really needs it.? He goes on to add that the crop is the ultimate sensor, and that ?we should ask the plant what it needs?.

This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return. The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.

There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us. ecoVaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.

Solutions to Password Overload

If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.

So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.

Why keeping passwords in memory is no longer possible

A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.

For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.

Remembering that one alone can be pretty daunting.

To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.

The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.

Password management solutions

Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.

Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.

But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.

Web-based password manager

A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.

If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.

With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.

Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
